22 JUNE 1966
The song was supposedly based on Bill Haley's 'Rock Around the Clock', but the trippy little burst of 'When will it end, when will it end' was pure 1966, a little dab of psychedelia.
This track was from their album Yardbirds (a UK title only, as it was called Over, Under, Sideways Down in the US and, confusingly, gained the colloquial name Roger the Engineer because of the drawing on the album cover).
