Music group Whitesnake are confident that they will be invited by legendary rock band Led Zeppelin to join them on a world tour.

The Zeppelin tour has been eagerly awaited ever since they performed a one-off gig in London last December, contactmusic.com reports.

Said David Coverdale, lead singer of Whitesnake: 'I'm expecting a call from Jimmy (Page, Led Zeppelin guitarist) any day asking my band Whitesnake to support them on a world tour. Am I on board? You bet! It's probably worth billions.'

Coverdale also thinks Zeppelin will be much better than the Rolling Stones in concert.

He added: 'Unlike rolling out the wheelchairs with the umpteenth Rolling Stones World Tour, a Led Zeppelin tour will be incredible.'
