I finally saw that Tom Jones, Will.I.Am, Thingymajig and Jessie J version.
I'm all for different interpretations, but this cover was horrid! I'm stunned to say this, but of that group, only Will.I.Am had the song "right". Tom Jones was signing another song. Thingymajig has the worse goat-bleating vibrato I've ever heard. I'm not sure what Jessie J. was singing, other than her scales.
If these are the "judges", then no wonder why the kids always sound confused and off-key.
It's these types of covers that I predict we'll hear a lot more of in the years to come - especially if U2 retires. Thank goodness they didn't try to belt out "With or Without You" - I'm not sure my ears could have handled the screaching at the end.
