The first song I remember hearing
Save the Best for Last by Vanessa Williams was used in a series of adverts for Bisto gravy in the 90s, where they poured the gravy in slow motion. For some reason, it was the first song that really had an effect on me.
The first single that I bought
I remember my mum giving me a pound to buy Wannabe by the Spice Girls on cassette from Woolworths in Stoke Newington [north London] when cassette singles only cost 99p!
