BBC Newsbeat reporter Del Crookes has issued an interview with METALLICA frontman James Hetfield. The following is an excerpt from the interview:

Q: How's the current tour going?

A: "We've only been out for a little over a year. We've got about one more year to go. It's the hump right here with one month over in Europe. We're obviously doing a lot of summer festivals, then heading back to the States. We've got South America to go. We've got more Europe. We've got Japan, some Asian things. We've got Australia and we'll see what happens after that."

Q: You're playing Knebworth as part of the Sonisphere Festival this weekend. Some famous Brits have played there like OASIS and ROBBIE WILLIAMS. What are your feelings about playing there?

A: "The same stage as Oasis? Woo! No. I tend to think about Knebworth as DEEP PURPLE and LED ZEPPELIN. Lars would be probably lump them [Oasis] in with the same group. It's one festival we haven't done yet and we're on this planet to play as many places as we can. That is next on the list. Metallica is grateful to be at the point where we can headline a festival like that. We're excited about it."

Q: What can Metallica fans expect? Will it be the same kind of show as your indoor concerts?

A: "No, no. Definitely not. When you're outdoors there's a whole different vibe. It really does depend. We have done a few shows in London already, so we'll take a look at the set list, see what things we've done nearby. We haven't done a whole lot. We did a couple of O2s, we did Newcastle, we did Sheffield and I think Manchester. We'll take a look at those set lists and try and throw in different things just so it's somewhat mixed up. You're not doing all the obscure songs that you normally would at an indoor show. You are doing some but not all of them. You do want to keep the crowd bouncing out there and keep them happy with songs that they kind of know but throw a few in for the hardcore fans. The show is the second of August and my birthday is on the third, so something might happen. It's interesting, my guitar roadie Shane shares the same exact birthday as me, so Leos attract each other I guess."
