It's getting close to my 24 hours now, CAM, and the UK is pretty much gone to bed so I'm going to do another five:

12. The Tide Is High - Blondie
15. Sweets For My Sweet - The Searchers
29. Carl Douglas - Kung Fu Fighting
31. Babylove - The Supremes
50. La Bamba - either Richie Valance or Los Lobos. Not sure who had the No 1 hit but I'll guess Los Lobos

I think I know 33 but Ill leave it for now.

I'll confess to a little bit of help from Mrs CT on these...
