Itchy-coo Park by the Small Faces...

The Sun Ain't Gonna Shine Anymore - the Walker Brothers...

If You're Going To San Fransisco (Be Sure To Wear Some Flowers In Your Hair) by Scott McKenzie... (I think that also qualified for the all-time longest title to make the 'Top Ten')

Another bit of trivia - 'Space Oddity' was the only 'serious' pop song to feature the dreaded Stylophone - without Rolf Harris!
