Discovered yesterday that my work colleague, of a similar age to me, has always thought that that the lyric to the Bonzo Dog Doo Dah Band's "Canyons of Your Mind" that goes:

'Cross the mountains of your chest
I will stick a Union Jack

was actually:

'Cross the mountains of your chest
I will lick up onion jam


Que??? Had to make him listen to 2 YouTube versions before he reluctantly conceded than onion jam does not feature in this song!
