Howdy there Mark.I checked the Tucson Friends of Traditional Music newsletter and found:

(1) Sat 2/19: Contra&Square Dance with live string band (The Privy Tippers) 7:45-11 PM at Armory Park Recreation Center just south of downtown (220 S. 5th Ave)entrance by donation (for info call 520-327-1779)

(2) Also, you might call the song circle number and see if they know of anything: 520-327-1779

(3) and since there's too many Bluegrass Jams around here to list in their newsletter, the following URL was given for checking out the possibilities there: http://home.att.net/~fertilepickens
