1980 Japan Tour

From RollingStone:

On January 16th, 1980, Paul McCartney arrived in Tokyo for Wings’ 11-date tour of Japan, his first visit to the country since the Beatles had performed there in 1966. But thanks to the nearly eight ounces of marijuana that he’d foolishly tried to conceal in his luggage, he wound up spending 10 days in jail instead. The former Beatle’s ganja gaffe not only forced the entire Japanese tour to be canceled, but also caused McCartney to drop his plans for Wings’ summer 1980 tour of the U.S., which would have been the band’s first stateside jaunt since 1976. The band unraveled from there without playing another gig, officially coming to an end when founding Wings member Denny Laine left in the spring of 1981.
