I actually saw Anvil back in late 80's at St Davids Hall in Cardiff. Think they were support band for Y+T (though it's a while ago so might be wrong on that info).
If i recall, 'Lips' their main guitarist/vocalist used a vibrator to play slide guitar, and they had a song 'Butter Bust Jerky' which surprisingly enough was about a woman spreading butter on her large chest !!! Just looked up the lyrics (they certainly don't make them like this anymore):-
All I need is a lady
	With more than average size
	She's gotta be a bit crazy
	Won't take no compromise
	If she can fill a "D" cup
	It's good enough to keep me up
Get you down on your backside
	I wanna see your wares
	Gonna mount you for a good ride
	Nothing else compares
	Takin' one into each hand
	Do as I command
Chorus:
	Doin' the Butter-Bust Jerky
	We're gonna get down and dirty
	Doin' the Butter-Bust Jerky
	And makin' me feel so good
Dip your fingers in the butter
	Spread it all across your chest
	In between one another
	You know what I like best
	Push 'em close together
	The tighter the better
