YOU CAN still catch the swinging balladeer Michael Bublé (pronounced Boob-lay) at the Blue Note in Greenwich Village doing two shows a night through Sunday. This young guy is the comer from Warner Records, who makes all the standards immortalized by Frank Sinatra, Bobby Darin and Dean Martin live again. Bublé has been on a classy high since he wowed everyone at my recent 80th birthday party! He sang that night with the likes of Liza Minnelli, Bette Midler and Tommy Tune. Not bad.
