Frank Sinatra?s contributions to the stage and screen were remembered Tuesday night in New York, as part of Sinatra at 100: Film & Music , the Tribeca Film Festival?s nod to a year-long national event marking a century since the singer and actor?s birth. Tony Bennett headlined a tribute concert for the late Sinatra, who performed for the last time three years before he died in 1998. In his lifetime, he appeared in 60 films and sang on 1,400 records. The 45-minute show at Spring Studios was preceded by a screening of On the Town, a 1949 MGM musical starring Sinatra.??
