Boybands Busted and McFly have joined forces for a joint UK tour in April and May next year.

But the former will be without Woodbridge’s Charlie Simpson who has decided not to join up with his erstwhile colleagues.

It is not known why Simpson won’t be involved in the tour, which will see the groups renamed McBusted for the duration.

However he did tweet: “Just wanted to say that though I am not joining @mattjwillis and @JamesBourne on their new venture, I wish them all the very best with it!”

The singer-songwriter, who went to Framlingham College in Suffolk, has embarked on a solo career and performed with band Fightstar since the members of Busted went their separate ways which has included playing the world’s coldest concert at a temperature of -30 degrees centigrade in Siberia last year.

Although Busted split up a decade ago McFly are still a band in their own right and will be releasing a new album early next year.

Matt Willis from Busted said: “It’s been nearly 10 years since Busted split. That’s a good amount of time for memories to gel in your mind - it’s fun to reminisce now, the right moment to revisit those songs.

“And to do it with McFly makes it more of an event. The coming together of two forces!”

The six-piece first got together during one of McFly’s tenth anniversary shows earlier this year but bookmakers Boylesports have already offered odds of 2/1 the tour will be cancelled due to poor ticket sales.
