The title is the same as that of a drum-based instrumental by Sandy Nelson and Richard Podolor from 1961. Director Justin Kreutzmann (son of the Grateful Dead's drummer Bill Kreutzmann) has borrowed the title for his movie: the single is referenced in the movie, and Sandy Nelson and at least one of his children show up in the movie.

The movie initially seems to be mostly about drummers and drumming, but I'm not sure the discussion of drumming got much beyond "I hit things!" and occasionally "rhythmically!" However, by the mid-point of the movie it began to feel a bit like "Messed Up Rock-and-Roll Drummer Dads and their weird relationships with their sometimes-messed-up kids." I guess someone has already taken that otherwise awesome movie title.

There are many, many famous drummers in this movie: presumably Kreutzmann knew a lot of them already. Bill Kreutzmann plays a big part in the movie, but we also have Taylor Hawkins, Mickey Hart, Stewart Copeland, Ringo Starr, and Steven Adler. Not to mention Jason Bonham, Nic Collins, and Kofi Baker, all sons of famous drummers (and drummers in their own right).

I didn't feel the movie uncovered any great truths, except perhaps that touring musicians are crap parents (which has nothing to do with drumming). There may have been something to be learned about lousy family relationships, which might have been fine, but that's not really how this movie is sold. It's full of drummers, but it still felt like a bait-and-switch.
