So you think the popularity of the band Oasis will tank with Noel being gone? In my opinion, no. I don’t think Noel leaving will hurt the band if you think about it. Liam sang the lead vocals in most Oasis songs and Liam is actually a great singer. Noel was the main songwriter of the band, he wrote most Oasis songs while Liam sang them all. Sometimes Noel will sing the lead vocals.
The best Oasis albums in their career were, “What’s the Story Morning Glory”, “Be Here Now” and “Dig Out Your Soul”. “Dig Out Your Soul” their newest record is surprisingly a really good one and I can’t stop listening to it.
Depending on if Liam gets a replacement to take over Noel’s spot and depending on the new Oasis songs, they could still be big even without Noel.
Band members changes. Look at Metallica, Rob Trujillo didn’t hurt Metallica at all by replacing Jason Newsted. It didn’t hurt Led Zeppelin’s comeback with Jason Bonham replacing his father John for that one reunion show. The members of Van Halen changes, and they are still going strong.
What I’m saying, a band can still be successful even when members changes. Liam will not break up Oasis, he’s either going to get a replacement or make it just a 4 piece band with Liam writing all the songs.
Will I still support Oasis even without Noel? Sure, why not. It all depends on how their material is without Noel. I’ve always been a big Oasis fan.

I tend to think, Kev, that Liam will soldier on with Oasis, if only to say “Screw you” to Noel. And, to that end, I’d expect a Liam-led Oasis album by the end of 2010.
While I’m curious about that, I’m far more interested in Noel’s solo album. He has some interesting material to work with — “Stop the Clocks,” “I Wanna Live in a Dream (In My Record Machine)” — that Oasis didn’t release, and perhaps unchained of the “Oasis sound,” Noel could unleash his experimental side.
The Times of London has a good article on how we got to this point, and what may happen next.
I agree, I look more forward to Noel’s solo album too, he’s going to make a great one, I’m sure. I’m sure Noel’s solo career will be more successful than Oasis.

Oh yeah, and I’m a huge Trekkie as you might have already seen, that is cool that you’ve written short Star Trek stories. You have a cool site too, by the way, Allyn.
