Remember what we discussed yesterday? Here’s something cribbing pretty heavily from it. What’s kind of extra sweet about this is it uses footage of the cast in their youth, long before (probably) they were characters on a show. (A similar thing was done - though I can’t find a video of it online - over the closing credits of the movie Knocked Up, with baby pictures of the cast and a few cast members with their own babies.) This kind of thing, though we know psychologically it’s actually the actors, establishes a world for us - these are the characters in their youth. This show’s continuity stretches backward in time forever.
The song, Forever Young by Bob Dylan, is a fantastic blessing, and one I have heard at no small number of Bar ‘n’ Bat Mitzvahs of the children of hippies. It’s not a reminder to stay actually young, but to always keep the adventurous, curious, and generous spirit that youth at its best can mean. A fully appropriate song for a show about three generations of a family watching each other grow.
