Bargain was a track from Who's Next and was allegedly inspired by Pete Townshend's spiritual guru, Meher Baba; I think the lyrics work just as well substituting a woman or a true love.
I put the video up to call attention to an outstanding piece of drumming by Keith Moon which I've never heard equalled. It's the part here where he comes back to close the song. Listen to how Moon pedals a bass line with both feet! He played double bass drums and perfected bass drum triplets, evident throughout the whole album, but most conspicuously there. You can hear John Entwistle dabbling in and out, accenting Moon's shin-cramping pedalled paradiddles.
