You're not wrong @FitYeDaeinYeMadRadge 
I'm not surprised Oor Wulllie won because I was privy to the following conversation between him and a Starstruck producer
SP: Hi William we got your application to be Ozzy Osbourne but we’re wondering if you’d be interested in doing Meat Loaf instead because we have two of those but only one Ozzy?
OW: No it’s Ozzy or I’m not doing it
SP: If we can guarantee you’ll win would you do it?
OW: Aye, nae bother
