Frank Sinatra would have been 96-years-old today. To celebrate, the Alzheimers Association is hosting a three-part gala fundraiser that starts at 2 p.m. with cocktails at Sinatra’s old Twin Palms estate in Palm Springs. Attendees will enjoy the musical stylings of Canadian jazz artist Matt Dusk. At 7 p.m., the party will move to the Riviera Palm Springs, where actress Pamela Anderson has volunteered to help donors part with their cash. Sinatra often partied at the Riviera. Appropriately, the entertainment will be provided by Frank Sinatra, Jr. and his Big Band Orchestra, along with Broadway star Lainie Kazan. And, there will be an after-party — naturally.
