For those who are prone to nostalgia for the “good old days” or who simply never got a chance to hear Frank Sinatra sing, the Buffalo Philharmonic Orchestra, under the direction of John Edward Liddle, teams up with Rick Sonata to play musical homage to Old Blue Eyes with a performance entitled "Absolutely Sinatra." Sonata, who has opened for Tony Bennett and Wayne Newton and was even characterized by Nancy Sinatra as “a dead ringer for dad,” is convincing both in physical resemblance and vocal likeness, so this event is sure to send the audience back to the days of the Rat Pack. The show starts at 8 pm on Friday (Oct. 20) at Kleinhan’s Music Hall.
