What's your favorite classic oldie?

Words of Love by Buddy Holly.

Short but sweet =)

Not sure if this is in the "Classic Oldie" genre yet but John Parr's "St. Elmo's Fire" (also goes by "Man in Motion").

"Crimson and Clover" by Tommy James & the Shondells. I heard the song when I was three or four on the radio and I've loved it ever since.

So many *-* The first one that comes into my mind, though, is "Video killed the radio star" by The Buggles.
