I can only assume that this lyric was triggered by some silly news story about men being exploited by the fashion industry.
I don’t think it was used but it does have one or two good lines in it.
_ PENIS IN BLUE JEANS _
(To the Tune of “Venus in Blue Jeans”)
INTRO – MELVYN BRAGG
Good evening and welcome to the South Bank Show. Politics and the performing arts. Tonight we welcome Ivor Tripod. Through his songs, Ivor argues that performers are exploited by powerful, faceless corporations. His first song tonight is a scathing polemic about the exploitation of men by the denim trouser industry.
(Enter female chorus)La la, la la la, la la la la, la la;
(Enter well endowed male singer) La da, da de da, da de de da, dee dum;
VERSE 1
My penis in blue jeans,
Macho Levis with a pony tail;
See the action in your swimming pools,
Of my cue and snooker balls.
VERSE 2
My Penis in blue jeans,
Outlined in a range of underwear;
Denim Wranglers can’t prevent the pain,
When horse-dragged cross the plain.
MIDDLE BIT
There’s more than seven wonders in the world,
Because my friend is number eight;
To keep my golden wonder neatly curled,
I must not masturbate…
VERSE 3
…my Penis in blue jeans,
Is a massively uplifting sight;
My pitch increases more and more,
(strains for the last few notes) These jeans are much too tight.
