Sounds like a reasonable opinion. Only one minor correction, 3 of them had solo careers but the other 3 went trio as opposed to solo. But he's correct in that no other group spawned so many separate platinum selling acts and yet come together as a platinum selling group as well. I can't put them ahead of the Jacksons though since they were so heavily influenced by them and Michael and Jermaine were two huge acts to come from that group. I'd say the Beatles, the Eagles, and the Bee Gees are other notable examples of bands with members to have successful outside projects.
