Gavin Rossdale has been "moved" by the reactions of younger fans during Bush's reunion tour.
The band are currently on a world tour after getting back together for the first time since 2002 and the singer feels honoured when their more youthful supporters praise their work.
He exclusively told BANG Showbiz: "When I come out and I see these people that loved us before and can't f****ing believe that we've started again - they just don't know how to take it. I'm getting all these sort of emotions, like gratitude, kind, hysteria and relief.
"Then we get people who say they were six years old when we brought our last record out and they say, 'I can't believe we get to see you' and 'I love your new record'.
"These guys think they make me feel old by saying it, but I gave my life to music and what they're telling me validates me. It's very moving in a way."
The 46-year-old rocker has been "fascinated" by the popularity of the reunion shows, so much so he thinks it has got "out of control".
He added: "The reunion tour is a like a juggernaut, it's a shocker, it's just out of control. It's out of control at the moment and I'm just trying to make sure we don't fall off the surfboard.
"I've grown up being taught to keep my expectations low, so it's been really fascinating to see the social phenomenon of this tour because you can't look at yourself objectively and think that you're any good. It's a weird thing to dwell on."
Bush are currently touring Europe in support of their new 'The Sea of Memories' album.
