Thanks again, everyone ... really nice comments!

Loren: much as I'd love to claim credit for it, I wasn't really going for replicating that particular sound per se, i.e. as it relates to the Haight-Ashbury style itself. What I did have in mind was a reasonably clear idea of the sound I was trying to achieve, and found that this particular BIAB style met my needs the most. But it's always great to find out the history of a particular style and movement - I spent a little time online researching this, following your comment, and came away enriched for it - so thanks!

I'll do my best to carry on having fun with music and BIAB ... I'm currently preparing a few BIAB arrangements of some public domain Christmas carols ... so I may post them on here when I'm done? Regardless, the main thing is, as you say, to have fun with music, I think ... so let's hope we all carry on doing that. Cheers once more!
