It was May the 16th, 1978, just before 3 days from the release of Dire Straits' epic single 'Sultans of Swing' which is in their self-titled album.
The band took the stage live at The Old Grey Whistle Test and performed that legendary, invaluable, and amazing song, Sultans of Swing.
This footage is one of the earliest footage of the band and it is beyond perfection since there was no release back in that time from Dire Straits.
The band's sound, playing, and whole live performance is just obviously amazing and it also sounds as great as the album version.
That's the way you do it.
