Was there ever really any doubt the dude could sing? I mean, come on.
He may have failed in channeling Michael Ball at the Les Mis weenie roast, but I'd never interpret that as no-talent. Maybe if he was an impersonator then I'd heartily agree he failed, er, miserably.
He oversang it (Pats AC126748 on noggin for being only soul to notice that). That's where the apparent constipation comes from and basically everything he gets accused of by the unobservant. XD He gave too much and ended up being accused of giving too little. Any singer knows that giving too much can sometimes give the effect of giving too little, so I don't really blame y'all, even if I do poke fun of you lot.
He was clearly trying to give at least a semblance of a Michael Ball sized performance. He'd have come across much better had he just stuck to being himself. It would have spared all from constipation looks and fake British accents.
But dude CAN siiiiing. :-P
