(Monday, March 24, 1975, 8:00 p.m.-2:00 a.m. PDT) — Former Beatle Paul McCartney hosted a party today celebrating the completion of recording sessions for the Venus And Mars album aboard the ocean liner Queen Mary, which is permanently docked in Long Beach, California, and converted into a hotel.

Among the 200 guests was fellow former Beatle George Harrison, marking the first time that George and Paul are seen socializing together since the break-up of The Beatles five years earlier.

Among the guests were Bob and Sara Dylan, José Feliciano, Marvin Gaye, Mick Jagger, Dave Mason, Micky Dolenz, Davy Jones, Carole King, David Blue, Cher, David Cassidy, Phil Everly, Jim Messina, Joni Mitchell, Harry Nilsson, Helen Reddy, Linda Ronstadt, John Mayall, Nigel Olsson, Paul Williams, Jim Webb, Richard Perry, Klaus Voormann, and members of several bands, including the Hudson Brothers, the Faces, America, the Jackson Five, Chicago and Led Zeppelin.

Tatum O’Neal and her father Ryan, Dean Martin, Tony Curtis and Rudy Vallée represented the Hollywood elite.

Harrison and his new girlfriend, Olivia Trinidad Arias, were there too, as were former Apple publicist Derek Taylor and onetime Beatles roadie Mal Evans.

Elvis Presley, John Lennon and Ringo Starr had been invited but did not turn up. John and Yoko were otherwise engaged in New York, and Ringo, having just wrapped up an acting job in Ken Russell’s eccentric Lisztomania (Ringo played the pope), was in London launching his new label, Ring O’Records, with Startling Music, an instrumental version of the 1973 album Ringo by former engineer David Hentschel.

Elvis Presley was perform two shows tonight (at 8:30 p.m. and midnight PST) at the Hilton Hotel in Las Vegas.

The party reportedly cost Paul about $97,000.
