Hmm ! My late father, who spent some time in 1944/45 commanding SP' Antitank Guns (M10's with the 17 pndr), and had previously trained and commanded a troop of Airborne 6 pndrs, used to sing a version of
this.

I regret that the only stanza I can recall was :-

It wasn't the Tanks that won the War,
The Anti Tank guns were there before,
With my boy Willie"

I think we could accept that unit rivalry between the Royal Tank Regiment and the Royal Artillery (Anti Tank) gave rise to this parody, but does anyone know either version ?
