Overview
The piece was performed live only a few times during the 1970 Pink Floyd tour; some notable differences from the studio version include being longer in length, some small screams from Roger Waters, a notable key change, and a David Gilmour solo played with a slide, before returning to its original key and theme at its ending.
The track is played at the beginning of the film, when Stefan is waiting for someone to pick him up along a road to Paris.
