They are some of the most talented and well-known men in the entertainment business.
And on Wednesday, former Beatles members Paul McCartney and Ringo Starr reunited for a night out with pals Tom Hanks and Joe Walsh, as well as their respective wives.
The iconic band's drummer, 76, looked in high spirits as he emerged from the lavish Giorgio Baldi restaurant in Santa Monica with the Eagles singer, with the rest of their A-list party hot on their heels.
True to his name, Ringo donned an all-black ensemble which boasted a white star on it.
He flashed a peace sign as he kept his beautiful former Bond girl wife Barbara Bach close by.
Joe was also dressed to impress in a chic great coat as he put a protective hand around his other half - Barbara's sister Marjorie Bach.
Sir Paul was spotted without his wife Nancy Shevell as he quickly headed to his car and was chauffeured away.
Joining the impressive line-up of pals was actor Tom who was suited and booted and added an element of geek chic with his specs.
He seemed to have enjoyed his night as he sped off with stunning wife Rita.
The Sully: Miracle On The Hudson actor has long been friends with the former Beatles bandmates and is seen with them on various occasions over the years.
Meanwhile Tom is set to star in the The Circle, a new thriller featuring Emma Watson and is focused on Silicon Valley.
The film, which is adapted from author Dave Eggers' 2013 novel, tells the story of Mae Holland (Watson), who goes to work for a behemoth tech company whose eccentric founder Eamon Bailey is played by the multiple Oscar-winner Hanks.
The Circle, also starring Karen Gillan, Patton Oswalt and Bill Paxton, hits theaters April 28.
Meanwhile, in December Paul filed a lawsuit in federal court in Manhattan on Wednesday against Sony/ATV over copyright ownership of the many hit songs he wrote with John Lennon as part of The Beatles.
The copyrights were famously bought by Michael Jackson in 1985 and then fully sold over to Sony/ATV following his death.
Paul has long wanted the copyrights, and the filing says he has sent notice to Sony/ATV saying that he will claim them back under a provision of U.S. copyright law that makes that possible after a certain time.
The first song eligible to be claimed back is Love Me Do, in October 2018. The rest of the catalog would follow in years after, ending in 2026.
