This could be considered an underrated 70's live album if not an underrated 70's album. It almost never comes up in discussions or lists of great 70's albums. I'll add Call Me Back and Beware My Love as my choices for "better live than studio" cuts.
Is there any detailed account of the overdubs on that album? Although I probably don't want to know about most of it. I'd like to think I'm hearing a live show of all that really happened. My guess is that the backgrounds are added to or altered. Who knows.
sorry to say, WOA was heavily dubbed. it was the norm tho, so it wasn't as if he was cheating. but if it is worth anything, i read that BITUS was the real deal. no overdubs at all. so...have a smile next time you listen to that one.
