Singing with the Muppets was the best day at the office that I've ever had

OVER his 25 years in music, crooner Josh Groban has played shows in some of the most famous and bizarre venues in the world, from his current Las Vegas engagement to appearing on set with The Muppets, and now the singer is in search of space.

Josh has received five Grammy nominations during his long career, after releasing nine studio albums, and has achieved three hit singles in the UK along with a UK number one album.

But after seeing pop star Katy Perry's short space trip in April, during which she sang Louis Armstrong's What A Wonderful World, Josh himself is keen to explore off-planet opportunities.

"I'd love to sing in space one day," says the US star. "I'd be very curious to hear how the voice sounds up there.

"If you're in a capsule kind of environment, then I guess the acoustics are probably set in stone, but there are very few places I wouldn't sing."
