This thread hasn't taken off...thought I'd add my two cents though.
Over the past few days I've picked up 3 45's (7 Inch)....
U2 - A Side: With or Without You, B Side: Luminous Times and Walk to the Water
Cream - A Side: Strange Brew, B Side: Tales of Brave Ulysses
Beach Boys - A Side: Beach Boys Medley, B Side: God Only Knows
I thought God Only Knows was the A Side...but after looking online, I guess it's the other way around....bought it for that song though.
