Pink Floyd, ‘Jugband Blues (Coda)’ – Best Hidden Tracks

Syd Barrett says goodbye to Pink Floyd in typically unconventional fashion. His only songwriting contribution to their second album, 1968's 'A Saucerful of Secrets,' falls apart (or spaces out, your choice) after just two minutes.

In its place comes first a squawking sound collage and then a completely different song, featuring the group's soon-to-be-fired former leader alone on vocals and acoustic guitar, asking, "And what exactly is a dream / And what exactly is a joke?"
