I'm not going to argue with Jack Bruce.
I like Redding as a bassist and agree he's underrated.
One of the problems with these polls in general and especially when you talk about bassists is that there's technical mastery and then there's using those skills to actually serve the song instead of just employing your chops for the purpose of wankery. A lot of times for a bassist all it takes is a couple of carefully selected notes played at exactly the right time. The instrument has one foot in the rhythm world and one in the melody world so when you play is sometimes more important than what you play ** Keith Richard is master of playing rhythmically. He doesn't play a lot of notes but he puts them in all the right places and often on offbeats unlike many rock bassists who play everything right on the beat.
I'm completely at a loss as to who you're talking about. The only twins I can think of are the Nelson brothers. I first thought Johnny and Edgar Winter but then remembered that they aren't twins.
** There's a cool story about Miles Davis asking the new members of his band what instrument they play. When each answered with whatever instrument they were hired to play Miles allegedly told them "No you are a drummer." That may be overstating it a little but Miles point is well taken. You can play Happy Birthday and miss a bunch of notes and it'll still be recognizable as Happy Birthday. Mess up the rhythm even a little and all bets are off.
