And he has a great voice for playing off the other guys leads or co-leads. Al especially..they have similar voices yet they work well off each other. A Casual Look, Winds of Change, Make it Big.
I've decided that in Make it Big, the end vocal interplay between Brian + Mike, with Mike getting close to a falsetto, is one of my all-time favorite moments in the entire catalog. I get the "feels" on that part almost as much as some of their very best material from the '60s. I'm odd like that.
That vocal arrangement is genius; I wonder if it was Brian's idea? I think I recall reading that he only came in for a brief cameo on that song. I wonder if those Brian/Mike vocals were arranged on the spot by Brian, or if it was some pre-existing arrangement (done by someone else) that Brian just came in to sing.
