The song is pretty catchy even if the lyrics are silly. It was very lucky for Bally as that one throw-away line in the song started them on the road to becoming #1.
The movie Tommy, however, is so aggressively bad that it is unwatchable unless you are deep into some serious mind altering substances. I watched it a few years back and although I really, really tried, I just couldn't make it all the way through to the end. What a load of crap...
