Steve Lamacq: Ever been properly tempted by the harmonica?
Noel Gallagher: I think Oasis might have had it on a couple of tracks, and I have written a couple of tunes which required some kind of harmonica. But it's a weird thing: I remember once when we did an after ... Oasis played the Hollywood Bowl or something in the '90s, and Dave Gahan turned up, and we had promised our really good friend at the time, Johnny Depp, that we would see with whom we'd do the Viper Room, and Dave Gahan from Depeche Mode had turned up, and said "Can I get up on stage with you?" And we were, like "Pfff ehhh", so I'm going off guitars, mate, as he pulled out from his powdered blue blazer a harmonica. And we were like, "Ohhh", "Ohhhhhh, I don't know what we're gonna do about this." I kinda left him. I said to Liam, "Y ou're gonna wriggle out of this one, I can't."
Steve Lamacq: Not taking the responsibility .
Noel Gallagher: Y eah, but we had a great night out with him, actually . There was the story that he'd overdosed, and it was a thing that went on for[ever] like, "He's dead", and then "He wasn't dead". And me and Liam were in a taxi in LA which is as rare as chocolate rocking horse, a taxi. We were going back to his house, and the taxi driver's saying, "Hey! Y ou three guys look like you're in a band! Bla bla bla!" So we said, "Y eah, we're in Oasis". "Oh!" And he went "I'm in Depeche Mode", and the driver just says, "Didn't your singer just die?!" Dave Gahan said, "No, I'M the singer!" And there was this brilliant, 5-minute, kind of back-and-forward of Dave Gahan having to prove that he was still living, while me and our kid were nutting each other , losing our heads [laughing silently].
Steve Lamacq: If only Dave Gahan had been wearing the full white suit. It could have been "Randall and Hopkirk (Deceased) "!
Noel Gallagher: No, if only we have had the iPhone and had been filming it in the back of the van, because he was going, "No, look mate, I am HIM! I am ALIVE! Am I not, lads?" And we were going, "Well, I don't know, I mean we have been out all night, I'm not sure whether [you're alive], let's check your pulse." And the guy was going, "No, I think I've seen it on the news", he was like "Y our singer died, right?"
