Vicente - Thanks for the listen. You called it, Robby is the singer and bass player.
Daren - Thanks, glad you enjoyed it. Wow, PR is one of my favorite singers, and I think Robby's, he should be thrilled with that compliment;)
Lynn - Thank you. Funny you mentioned Journey, I never heard that quality in the vocals until you mentioned it. Now I can't not hear a little SP in it.
TheBand19 - The bass certainly contributed to the song but I think stating that the bass "made the song" is going out on a limb a bit

I would give you this, the vocals made the song...
Ed - Thanks, I knew eventually I would get one out that sounded good to you;) This forum has been invaluable for learning the art of mixing. The playing is much easier, and more fun than the mixing,
I have to admit. Herb - Thanks for the listen, I tried to play this a little more laid back than the 1975 BC version. I saw BC do this live and they did it a little more like this version than their original recording. I was surprised to read that BC never released Silver Blue and Gold as a single, even though it is one of their more popular songs.
