Artists who insist on singing their songs in the wrong language

Actually, I think the Three Tenors singing in English is just wonderful.
I laugh my arse off.
Anybody remember John Candy on SCTV. He did a takeoff of those late night greatest hits TV commercials.
He played Pavarotti singing classic rock in English. Smoke on the Water, Stairway to Heaven.
When Pavarotti sings in English he sounds just like John Candy.
It kills me!
