This might help clear up some arguments as to whether Gem and Andy's influence on the band is a good one or a bad one:

(no particular order)

1. "A Bell Will Ring" - Amazing song. Sounds like the Beatles. One of the best Oasis songs ever, in my opinion.
2. "Love Like A Bomb" (Gem co-wrote) - A perfect summer tune.
3. "The Quiet Ones" - Cool acoustic tune which I think doesn't get enough credit. It has a weird feel to it, a kind of weirdness Noel can't really get.
4. "Eyeball Tickler" - Amazing tune. A proper rocker. Didn't even make the album but this could be an opener.
5. "Hung In A Bad Place" - A proper rocker. Very cool groove, which you don't find usually in an Oasis song.
6. "Thank You For The Good Times" - Another one that doesn't get enough credit. It has that Ride sound which is something Oasis is quite good at. Very solid.
7. "A Quick Peep" - Certainly the weekest of this list, but when you take it for what it is, a 1+ minute instrumental, it's a nice change of pace in the middle of the album.
8. "Keep The Dream Alive" - Speaks for itslef. Amazing song with a melody that can melt your soul.
9. "Turn Up The Sun" - Speaks for itself. Proper rocker. The best opener Oasis has ever had, by far.

I'd say they've had a great influence, wouldn't you? These nine songs would make for a hell of an album!

*Let's not forget that Gem is ten times the guitarist Bonehead was, and Andy ten times the bassist Guigsy was.
