I fell for an April Fool's joke

I can usually spot a prank, but I totally missed this one.

A friend's band page featured an abject apology for 'stealing' a song from a guitarist he met on a French camp site. It was well-written and seemed plausible. Not because my friend is a theif, but because he would 'fess up to his errors.

It turned out to be completely fictitious, although it has somewhat backfired, as he's worried that someone will actually spot their own riff in one of his songs and sue the pants off him. Nice one!
