I have only two of the original 45's that I purchased (for a dime!) back when I was in kindergarden...
Sam the SHam & the Pharoes - Wolly Bully
The Trashmen - Surfin Bird
Both are just beat to a pulp as we played them a lot during 'indoor recess'. And they still have my name written on them by my teacher, back from before I could write it myself!
