I have to confess, Auto-Tune hasn't improved musicals...

Back in the day, they'd get a GREAT singer to dub in the musical numbers if an 'actor' couldn't cut it. Nowadays, they just use the actor, and then electronically try to create a silk purse out of a sow's ear.

Not that successful, IMO...

What's next? T-Pain doing Porgy and Bess?
