If you haven’t yet caught up with the documentary Young@Heart, which looks at a senior citizen’s choir that specializes in rock songs, you can do so tonight when it is featured on PBS’s Independent Lens series (check here for local broadcast times).

With an average member age of 80, the Young At Heart Chorus could be the oldest rock outfit still performing. (Please note that I am avoiding any obvious Rolling Stones jokes.) With a set lists that cover James Brown to David Bowie to Talking Heads to The Clash, the group is no mere novelty act. While most of the members were probably too old to appreciate their repertoire when it was released, they sure have a new found understanding of the songs now. They may wince when choir director Bob Cilman pops Sonic Youth’s “Schizophrenia” into the CD player, but as they begin practicing the song, they slowly discover it and make it their own. At some point you realize that the chorus members are having so much fun, you don’t care if they perfect the songs in time for their upcoming concert gig. You just bask in their joy of making music together. At times loving and heartbreaking, the two hours you spend with this film is probably better spent than if you watch the season premier of a certain singing talent show tonight.

Last year’s documentary Young @ Heart is being adapted into a feature film by Working Title Pictures. Although no director has been signed to the project, the production has brought on board Will Reiser, a former producer of Sacha Baron Cohen’s The Ali G Show, to script.

Director Stephen Walker and Sally George’s film follows a senior citizens’ choir that specialized in rock songs. We get to know several of the members of the group as they prepare several new songs for an upcoming concert. And while they don’t overly manipulate the pathos that is found in their stories, if you don’t tear up, then you may want to check your pulse.

Honestly, I don’t care who is writing this, as I think it is a terrible idea. Nothing can be more dramatic than real life and the rising trend of turning documentaries into fictionalized features only emphasizes that. A fictionalized retelling only serves to build an air of artifice around the actual drama, laughter and heartbreak that the documentary captured so effectually. Sure, there have been plenty of films that have been “Based on a true story,” but why make a film based on a true story when there’s already a film that directly documents that story?

When Jethro Tull lead singer Ian Anderson sang “You’re never too old to rock and roll, if you’re too young to die,” he probably never envisioned the members of Northampton, Massachusetts’ Young At Heart chorus, but its members certainly fulfill that credo.

With an average member age of 80, the Young At Heart Chorus could be the oldest rock outfit still performing. (Please note that I am avoiding any obvious Rolling Stones jokes.) With set lists that cover James Brown to David Bowie to Talking Heads to The Clash, the group is no mere novelty act, as is attested to by the group’s concert that we spend the film watching them prepare for.

Most of the members were probably too old to appreciate their repertoire when it was released, but they sure have a new found understanding of the songs now. They may wince when choir director Bob Cilman pops Sonic Youth’s “Schizophrenia” into the CD player, but as they begin practicing the song, they slowly discover it and make it their own. At some point you realize that the chorus members are having so much fun, you don’t care if they perfect the songs in time for their upcoming concert gig. You just bask in their joy of making music together.

Director Stephen Walker’s camera work insinuates itself into the group fairly seamlessly, taking us along for the fast-paced ride (some times literally) as the group gets ready for their show. The film never tries to condescend to the material or play things too cutely. Sure there’s maybe something darkly ironic about one of the choir members forgetting his solo lines to Jimi Hendrix’s “Purple Haze” of all songs, but moments like that are never played for laughs.

Young@Heart doesn’t shy away from the fact that for all their energy and devotion to the group, its members’ health can be a fragile thing, a fact that is soberly brought home when they lose not one, but two popular members in a close space of time. But the rest of the group doesn’t let such a setback serve as an excuse to cancel their upcoming gig. Rather, they live up to the old show business maxim and go on with the show, knowing that’s what their departed friends would have wanted and saying it’s what they would want the group to do when their time comes. These performances become a way for the group to simultaneously mourn and celebrate their friends, culminating in a hauntingly beautiful cover of Coldplay’s “Fix You” in the film’s finale concert.
