David Gilmour/Roy Harper - Short and Sweet, live in 1984 

In 1984, one year after Pink Floyd's last album 'The Final Cut', David Gilmour put out his second solo album 'About Face'. He had a band that consisted, among others, of Steve Winwood, Pino Palladino and Jeff Porcaro. I can spot Pino Palladino sporting his trademark fretless bass in this video, but the others I don't know.
The band plays 'short and sweet', which was featured on Gilmour's first solo album, that came out in 1978 and was called 'David Gilmour'. The song was cowritten by the enigmatic Roy Harper, who joins the band on stage in this 1984 performance of the song.
