Called "Growing Old Along With Me," the prescience of Lennon's song to the septuagenarians Starr and McCartney is multi-faceted.
In a news release, Starr explains that the song was brought to his attention by producer Jack Douglas, who also recorded Lennon and Yoko Ono's 1980 album, Double Fantasy.
"Jack asked if I ever heard the 'Bermuda Tapes,' John's demos from that time," Starr said. "And I had never heard all this."
Lennon originally wrote the track as a tribute to Ono. And Starr says it was emotional, working on one of his former band mate's songs. McCartney played bass and added some vocals of his own.
"I sang it the best that I could," Starr added. "I do well up when I think of John this deeply. And I've done my best. We've done our best."
But there were four Beatles, not three, and with the help of some creative arranging from Douglas, they included George Harrison as well.
"So, John's on it, in a way," Starr said. "I'm on it and Paul's on it. It's not a publicity stunt. This is just what I wanted. And the strings that Jack arranged for this track, if you really listen, they do one line from [Harrison's] 'Here Comes the Sun.' So in a way, it's the four of us."
The album is due out October 25.
