Sting in Quadrophenia and another awful movie he did (it) with Meryl Streep (who puts on an English accent ... Sting puts on a Southern Engish accent too; I can't decide which was worse).

And who can forget Mick Jagger as the Australian Outlaw Kelly doing the Irish/folk song "Wild Colonial Boy."

Then again some actors should have gone into singing: Edward Woodward should have given up acting and done opera instead of the 80s TV show "The Equalizer."

Cheers, Brian
