Paul Kantner, as one of their weaker singers, the guy who wrote harmony songs, not just leads, was the one who tried to get everybody singing and playing at the same time, if not always in sync. "We Can Be Together" sounds too ferocious and has too much desperate posturing for a we-should-be-together song, which is appropriate, as neither band nor scene is going to hold together much longer.* Kantner's the one who tries hardest and longest to keep the ideals real.
*That's why I'm embedding it. Of the Kantner-only writing credits, I like "The Ballad Of You And Me And Pooneil" and "Crown Of Creation" just as much, but the latter is too focused for what I'm trying to say, and too much of a take-down of a "them" rather than a wrestling with a difficult "us." The former has too much optimism. Its "You and me we go walking south, and we see all the world around us" changes in a few months ("House At Pooneil Corners," co-written with Marty Balin) to "You and me we keep walking around/And we see all the bullshit around us." "We are leaving, you don't need us," on "Wooden Ships" comes a few months after that (by Kantner and Steve Stills and David Crosby), same alb as "We Can Be Together" and is just as much posturing and just as desperate. Backs against the wall so we retreat to fantasy, 'cause the wall's not coming down.
"I can carry my friends and I do when I can, we get by however we can."
Paul Kantner, March 17, 1941 – January 28, 2016.
(I didn't stay listening to Kantner and crews much beyond 1972, if any of you would like to point me towards what's most interesting in what came after.)
