Kiss sticksman Eric Singer admits to be really dissapointed in haters, bashing the band's current lineup.As Classic Rock reports, Singer has hit out at fans who complain about the fact that the band's current line-up does not feature Peter Criss or Ace Frehley:"The people that want to complain about 'I don't like this,' or 'I don't like that,' 'They should play this song,' or 'I only want the original band...' The bottom line is: this is how Kiss exists right now, in 2013. Be glad there's some version of Kiss and that we're out there touring."We have just as much passion and case just as much as the band ever did or ever could. That's what counts. If we didn't, we wouldn't be here. I mean, Gene and Paul dont need the money; they dont need to do this. They do it because they love doing it.Singer is also tired of people asking about the band's future:"Everybody wants to ask what's going on tomorrow," says the drummer. "Well, what about today? You don't necessarily know what's going to happen in the future. But one thing's for sure: we're here today and we're going to put on a great show.I'm not saying don't have to think about tomorrow but you can't worry about tomorrow. Just live one day at a time, try to learn to live in the moment."
