OK, Spannish Fly, years since I heard it but isn't that on a steel? Nuno Bettencourt's "Midnight Express" (from the album "Waiting for the punch line" which has some great lyrics and some blistering soloing) certainly is, I don't know if that's tapping or not but it scares the **** out of me.
Best Acoustic guitarist I have ever seen was a classical guitarist called Galina Vernigora, an eastern european who happened to be touring low key venues like my local theater. That's kinda like finding Alain Robert* on your bungalow roof! Totally world class player, totally ridiculous venue.Here's a site with a bit about her.
