Go on, write another verse complaining about singers ripping off your parody-version. Then if it gets further you can finish the song with "And s/he even ripped off my complaint..." That should get a laugh.

LOTS of people have claimed to have written Pat Cooksey's 'Barrel of Bricks'(or the other 12 titles) and it irritates him too.

There was a time I used to say "There's an Irish copyright on this song. If anyone pinches it, me and Sean and Mick and Igor are going to beat the bejasus out of him!"
