Get ready to see an entirely new side of Kevin McKidd.

According to Fancast, Owen croons a bluesy tune when Kevin makes a tiny cameo in the final, January 21 installment of the Seattle Grace: On Call webisodes.

But try not to read too much into it, he says.

"It kind of ties in loosely with the [Grey's Anatomy] episode airing that night – but very loosely,” McKidd said, noting that the tune he was given to sing was “a really nice number” – and, more importantly, written by someone other than himself.

“Initially they asked me to write something,” he said, “and I was like, ‘There’s no way I’m going to sit on network TV and sing a song I wrote in my bedroom.’”
