• Lennon recorded this as a home demo on a cassette tape in the late 1970s, and had planned to record it properly on the follow-up album to Double Fantasy. Unfortunately he was killed before he could record a studio version. Yoko Ono released his single-track version of this on the Milk And Honey posthumous album in 1984. Later she asked Beatles producer George Martin to score an orchestral arrangement for this to use on the 1998 Lennon Anthology set.
• Paul McCartney wanted to make this the third Beatles "reunion song," but producer Jeff Lynne told him this would be very difficult because of a hum on the cassette that couldn't be eliminated. Also, George Harrison objected because it was too sad, given the nature of John's death - Yoko couldn't "grow old along with him," as the song urged. >>>

• Yoko Ono explained the origin of this song in the liner notes of her 1983 album Milk & Honey: A Heart Play: "One early morning in the summer of 1980, I woke up with 'Let Me Count The Ways' ringing in my head. I called John who was then in Bermuda and played it over the phone. 'How d'you like it?' 'I really like it. It's beautiful.' 'How about you writing one with a Robert Browning line and we'll have portraits of us as Elizabeth and Robert on the cover?'
  John called me that afternoon 'Hey, you won't believe this!' He explained that he was watching the TV, a '50s film of a baseball player. In the film, John saw the girlfriend send a poem to her baseball player, a poem which was one by Robert Browning called Grow Old Beside Me. 'Can you believe that?..so anyway, this is my version.' John proudly played his song over the phone. That's how our two songs happened."
• This is a very romantic song that's not about blinding passion, but about caring and commitment. It's a very popular wedding song.
• Mary Chapin Carpenter and The Postal Service recorded popular covers of this song.
• Ringo Starr covered the romantic ballad for his 2019 solo album, What's My Name. His version features bass and backing vocals by Paul McCartney and a guitar solo by Ringo's brother-in-law, Joe Walsh. Jack Douglas, who produced Lennon and Yoko Ono's Double Fantasy album, did the string arrangement.
  
  Speaking with the UK's BBC 6 Music radio channel, Starr revealed that he decided to record "Grow Old with Me" after Jack Douglas gave him Lennon's demo of the song, which features an unexpected message.
  
  Starr recalled, "At the very beginning of this CD (of demos), John says, 'Oh, that sounds like a good song for Richard Starkey. This would be great for you, Ringo.' I still well up thinking about."
