The singer is leaving the band due to "increasing writing and production commitments for other artists".
A statement on the Gun Myspace profile reads as follows:
I have had a fantastic time working with Jools and Dante and consider the music we have created together as being amongst the best I have been involved in throughout my career . I wish them well and sincerely hope that we will work together again in some capacity in the future. I stress that that I am in no way leaving the world of live music, far from it, it is simply that at the moment I cannot commit 100% to future GUN plans and would not want to stand in the way of the bands potential further development . I fully intend to resurface as a rock singer in one way or another in the near future so watch this space...
Toby Jepson
In a seperate statement, Jools & Dante from the band went on to thank Toby for being an excellent frontman and are now taking some time out to decide Gun's future.
