Short answers, pulled from the story.
Wings formed in London in 1971. The original line-up consisted of Paul McCartney on vocals and bass, his wife Linda McCartney on keyboards, Denny Laine on guitar and vocals, and drummer Denny Seiwell.
"Mull of Kintyre", released in 1977, became the biggest-selling Wings single. It was the first UK single to exceed 2 million in sales, surpassing the Beatles' "She Loves You", and ranked fourth on the official all-time best-sellers list for the UK in 2002.
McCartney was arrested on the 16th of January 1980 upon arriving at New Tokyo Airport, where customs found 219 grams of marijuana in his luggage. He spent ten days in jail before being released without charge on the 25th of January and deported, which forced the cancellation of a planned 11-date Japanese tour.
Wings had six number-one singles on the Billboard Hot 100. Their US chart-toppers included "My Love", "Listen to What the Man Said", "Silly Love Songs", "With a Little Luck", and a live-recorded version of "Coming Up".
Laine left in April 1981, citing the absence of touring plans. His departure was also driven by longstanding financial grievances, particularly that he had been paid a flat fee rather than royalties for co-writing "Mull of Kintyre", and by personal tensions between his wife and the McCartneys.
Band on the Run was recorded at EMI's eight-track studio in Lagos, Nigeria, after two members abruptly quit the band in 1973. The album reached number 1 in both the US and UK and is widely credited with restoring McCartney's critical reputation following years of dismissive press coverage after the Beatles' break-up.
