MEGADETH mainman Dave Mustaine has issued the following update:"Well, we were finally able to let the cat out of the bag and post that we are going to be playing on September 17 on the ['Late Night with Jimmy Fallon'] show in New York. "I am so pumped to do this show, because I have done several shows before, like 'FX', 'Jon Stewart', 'Politically Incorrect', 'Arsenio', and the great 'Dave Letterman' (and there was obviously the rush of 'Letterman'), but few were as fulfilling as being on Bill Maher or Jon Stewart's shows. "I am sure that there is going to be quite a lot to talk about soon, as I am having to make a considerable adjustment with my business and personal chops for this new record and this next tour; basically starting over. "I have been going over every stitch of my stuff and preparing for a much leaner tour and a much more efficient approach to MEGADETH, and my life in general. It has been really interesting going over all of the stuff in the studio for the last year, as well as my personal stuff. There are years' worth of memories, as well as tours and tours worth of stuff out in the warehouse. "Willie Gee (yes, the world-famous Willie Gee — he is not my tech, I actually play guitar for him) has been here for a few days, and has been going over everything with a fine tooth comb. He has found tons of stuff that we have troubleshot and fixed and we are almost done with all of the gear in the entire place — studio included. I am going to have him go over his dreads with the fine tooth comb next! "I am also very excited about the Pacific Rim tour. There will be terrific shows in Oz and New Zealand with us and SLAYER, which is a great concert for our friends Down Under (SLAYER are definitely amazing to watch), and there will also be some shows that we are both doing separately; like the Loud Park day, we are on different days, and there are some other shows in the Pac Rim that we added in Japan, and I was just thinking about how excited I am about the new band, the response to the new [MEGADETH] record ['Endgame'], and the fact that we are playing really well. "I had a meeting with Chris [Broderick, guitar] and James [Lomenzo, bass] yesterday and I talked with Shawn [Drover, drums] on the phone today about us changing our approach to our stage, and our performances. We decided that there were many more songs that we all would like to take a stab at. So we went over all of the back catalogue, and we decided, beside the 12 that makes up the co-headlining set with our friends in SLAYER, there were 30 extra songs we wanted to try to play over our next world tour; including the new ones from 'Endgame'. "I shall be making several announcements next week, mostly good, and I look forward to talking with you later."
