Following Lennon's murder in December 1980, Harrison modified the lyrics of a song he had originally written for Starr, "All Those Years Ago", as a tribute to their former bandmate. Released as a Harrison single in 1981, the track, which included Starr's drum part and overdubbed backing vocals by McCartney, peaked at number two in the US charts and number 13 in the UK. Later that year, Starr released "Stop and Smell the Roses", featuring songs produced by Nilsson, McCartney, Harrison, Ronnie Wood and Stephen Stills. The album's lead single, the Harrison-composed "Wrack My Brain", reached number 38 in the US charts, but failed to chart in the UK. Lennon had offered a pair of songs for inclusion on the album – "Nobody Told Me" and "Life Begins at 40" – but following his death, Starr did not feel comfortable recording them. Soon after the murder, Starr and his girlfriend Barbara Bach flew to New York City to be with Lennon's widow Yoko Ono.
