50: The Bonzo Dog Doo-Dah Band, “I’m the Urban Spaceman” (no.5, 1968)

The first of Neil Innes’ two one-hit wonders (followed a decade later by The Rutles’ “I Must Be In Love”), co-produced by Paul McCartney; and it’s reassuring to think that, with the streets of Prague and Paris on fire and America drifting into wistful or wig-out psychedelia, Britain was holding the fort with gentle, approachable eccentricity such as this. The self-negating twist of the final line arrived thirty years before The Sixth Sense, you’ll note.
