You mean these things weren't blatently obvious to you already? :green:
The solo and the BGV's in the cans sound like they were the real ones, which means Dave was possibly the last one to track. Also sounds like the tape was stored "heads out" AND "tails out". You can also hear alternate/additional vocal takes that either didn't get erased completely, or were escaping through his cans. Cool...
Obvious punches were pretty common place in that era, even when accompanied by loud music. Think about it... the choices were not very plentiful. Go for the "once in a lifetime" vocal take, or go for the technically better take and risk not being able to get a better take. Decisions were a lot tougher, and a lot more "final" than they are now. Sometimes I miss those days... sometimes I don't.
Back then, it was easy to mask a punch by executing it on a snare hit... even in the middle of a word. Listen closely, and notice that all of the punches land on beats 2 and 4... :wink:
