This sounds interesting... it's about this music group (Young At Heart Chorus), as they go on tours and sing covers of songs from various decades, from the classics to ever contemporary stuff like Sonic Youth, Coldplay and whatnot.
The interesting part is the average age of the people in the group is eighty. Yes, eighty. Despite that and various health problems and other heart-breaking events, the group still manages to perform (even in places like correctional centers and whatnot) and learn new material.
I checked out the trailer and it sounds pretty neat. Not sure I'd see in the theater (course, I don't see too many films in the theater these day) but I'd definitely catch it on video.
