After the Who released Tommy - and toured with it relentlessly - they had to come up with a worthy successor. Pete Townshend worked on an ambitious project he was calling 'Lifehouse.' It was not to be as the next Who album. Some of it got released as a series of singles. Some showed up on Townshend's first solo record 'Who Came First.' A lot of it ended up forming the backbone of 'Who's Next'
The recurring theme of 'one note rules us all' crept up in a lot of these.
The following singles are referred to as the 'Lifehouse Trilogy'
1. Let's See Action b/w When I Was a Boy
The first one. A version appears on Pete's solo record, but this is the definitive Who version. B-Side is written by John Entwistle. It was common for the Who to give the B-Side to a non-Townshend composer. Since royalties were distributed equally between A-Side and B-Side, the composer of the B-Side gets a cut even if only the A-Side was a hit. UK pressing of this one. I don't think it was ever released in the USA.
2. The Relay b/w Wasp Man
The second one and one of my favorite Who tracks. Still gets an occasional airing in their post-Keith Moon shows. B-Side is by Keith Moon and is primarily an instrumental riff with Moon repeating the word 'sting.' I tried to get the sticker off. Honest. It might have another year or so worth of work left.
Extra Bonus - Here's a picture sleeve I have. Art by Ralph Steadman. Somebody penciled in the names of the band members, but they got 'em wrong. Couldn't spell Daltrey's name right on this one either.
