Not really true like, most songs were joint efforts aside 3 tracks on Second Coming acredited solely to Squire. King Monkey only started playing Stone Roses stuff again a few years ago he hadn't played it on solo tours at all until that point, didn't want people to think he was living off past success. Squire however, talented bloke and great guitar player that he is, played the Roses stuff for years because he couldn't write anything decent.
Now Brownie plays a mix of Roses and solo stuff. I've seen him live over ten times, it's always superb! %)
You should listen to it, all the albums are good. All quite different albums too.
