A few more songs about Buddy Holly:

Tribute to Buddy Holly by Mike Berry
I Feel Like Buddy Holly by Alvin Stardust

Three Stars by Eddie Cochran was about Buddy, Big Bopper and Richie Valens.

Then there was Just Like Eddie by Heinz (about Eddie Cochran).

And then there was "A Million Housewives Every Day, Pick Up A Can Of Beans And Say, Beanz Meanz Heinz" :-)
