I'm trying track down a couple of tunes Charlie played on his show in GLR / BBC London days.
The 1st is a dancey tune called (I think) "Blow Your Blues Away" by Little Twitch (or Titch?) I seem to recall Charlie bringing a vinyl copy of this to an early DJ Relay for someone else to play as part of their 15 minutes.
The 2nd is by Jamaican singer Spanner Banner & is a poppy reggae tune called "Cheater" I've found reference to its existence on the net, but haven't been able to find a way to listen to or download it.
I remember that Twitch tune.
Robert Elms also played it a lot and there's even an old 2002 Radio London link to Gary Crowley naming it his single of the year with thanks to Charlie for introducing him to it.
I'm sure you've already found this via Google, but here's the story of the song
I can't find an mp3 link, although I've got it somewhere, burnt on CD many years ago.
