OK, Lin. The guilt got to me, since you're such a nice person, and I went through the three shelves where my David Wilcox CDs are supposed to be. Mr. Database tells me I have four Wilcox CDs:

Home Again
Big Horizon
(Mostly) Live-Authorized Bootleg
How Did You Find Me Here

But I can't find any of them. All are on the A&M label. I really think that allmusic.com has all the credits information I'm likely to find on the CD booklets. Although I'd love to be able to help you, I don't know where to look. Most of my CDs are ripped, and they're stored in a place where the map says, "Beyond here there be dragons."
Sorry I couldn't help.

David Wilcox has a Website with a contact page. Why not contact David and ask? You may get a delightful response. That's the thing about folk musicians - most of them are pleased to correspond with you.
