Help!!

In the mid to late 90's there was a sketch show on which featured, as I recall, a sketch in which an old diva was asked back into the studio to record a new "James Bond" type theme. As I remember it was quite a long skecth and when the song was eventually played there was very little of her recording used in a rap song. Anyone have any idea what this was 'cos it's driving me mental and I want to see if it's as funny as I remember??? Please help!
