I’m pretty sure this wasn’t used. As much as anything else, another of my lyrics that works to “He Ain’t Heavy, He’s My Brother”, the Princess Di Bulmia Song, was a perennial in the show at that time:
Anyway, this was presumably intended to be a quickie and to echo the other “Heavy” number.
IT AIN’T LEVY, IT’S A PLUNDER
(Quickie to the Tune of “He Ain’t Heavy, He’s My Brother”)
The road’s gone wrong,
It’s blemished with dire sun burn;
Our motorways from the start,
Fall apart.
Delays long,
And we’re asked to pay for them;
It ain’t levy,
It’s a plunder.
