Please Help Before I Go Mad !!!!!!!

Hello, can anyone help me find the name to an old reggae song ??
In the middle of playing the song the band is interupted by someone coming into the studio, one of the band members asks if he can play bass, no is the reply, ya cant play bass ?? Leave the studio man leave the studio is the reply and they carry on playing the song.
Can anyone help, before i pull all of my hair out.

sounds like scotty and 'skank in bed'

if you've ever heard breakfast in bed(lorna bennet) or the ub40/chrissie hynde version then you will perhaps recognise the riddim
