well, you find links in the most interesting places! I was reading my newsgroup alt.crafts.woodturning, when someone mentioned as an aside his son's site here where there are some old records with the likes of Big Bill Broonzy, but tending towards jazz...this had links http://www.dnai.com/~swazoo/sites.html to others, especially to

this amazing place where you will find almost anything to do with old records...tech, samples and more links, such as this one and this other one
a lot of these are to old jazz, show tunes and such, but there is a wide mix!
(he has Honking Duck as a link BTW)....there are a few dead links, as you might imagine, but....WOW!

have fun...don't get lost now....*grin*
