So you can't wait to buy his CD ("Slow Dancin'") and can't wait to chat with him on Playbill On-Line (Oct. 27), and you still can't get enough Tommy Tune? Why not meet him in person, Oct. 28, at the Lincoln Triangle branch of Barnes & Noble in NYC? Tune will be there, 7-8 PM, autographing copies of his autobiography, Footnotes. One assumes he'll also sign CDs, since Oct. 28 is the release date for both the RCA Victor disk and the Simon & Schuster bio.

Also scheduled for Barnes & Noble will be Jackie Mason (Oct. 17, Upper West Side branch ) and Jaffe Cohen (Oct. 20, Lincoln Triangle branch). Mason's Broadway stand-up comedies include The World According To Me and Politically Correct. Mason is appearing with laywer Raul Felder to promote their "Survival Guide To New York City." Cohen, who is promoting "The King Of Kings And I," was a gay playwright before co-founding the sketch comedy troupe, "Funny Gay Males."
