I just now found out what this is...People have been singing it to me cus my name is Trevor...Like people sing out the first line or two at me and I am like "Huh....WTF?"
Everyone loves Magical Trevor,
'cos the tricks that he does are ever so clever,
Look at him now, disappearing the cow,
Where is the cow, hidden right now?
Taking a bow, it's Magical Trevor,
Everybody's seen that the trick is clever,
Look at him there, with his leathery, leathery whip,
It's made of magic, and with a little flick,
Yeah, yeah, yeah, the cow is back,
Yeah, yeah, yeah, the cow is back,
Back back, back from his magical journey.
What did he see, in the parallel dimension?
He saw beans, lots of beans, lots of beans, lots of beans,
Oh, beans lots of beans, lots of beans, lots of beans, yeah yeah...
