[ikeypygo]

Okay the film sid and nancy, there is a song which plays a few times through the film there is no singing in it but there may be lyrics later on in the song, now one of the scenes when it plays is about half way through the film when sid and nancy are in america and nancy is leaning against a skip type thing in an alleyway sid is with her and they are kissing there is rubbish falling around them, the second scene is at the end of the film when sid is just released from jail and he stops at a small cabin/cafe type thing with pizza written on it there are some kid's listening to a song dancing and sid joins in then a taxi arrives with nancy sitting in it he gets in and they kiss , the music is playing then can anyone tell me who the song's artist is and what it's called ?
Thank you if you can help

If its the clip i`m thinking of,when Sid dances with the kids?Its KC and The Sunshine Band-Get down Tonight,then when he gets into the cab its Taxi to Heaven by Pray for Rain.
