I was thinking about this sort of thing the other day, the Pat Boone sings Sandman type travesty, and wondering how things would have worked out had bands done what they do, say Sabbath or whomever, and not jazz it up or add an orchestra or synth but, just had this person singing the real songs. Something like;
Cindy Lauper instead of Tom Arraya
Tom Arraya in ABBA
Curt Cobain singing lead for Pink
Madonna lead singer for White Zombie
That sort of thing...
You think too much.
