What is "rockshow"

Rockshow is a 1980 concert film by Paul McCartney and Wings, filmed during the band's 1976 North American tour. The film features 30 songs from four concerts of the tour: New York, on 25 May (four songs); Seattle, Washington, 10 June (five songs); and Los Angeles, California, 22 June (fifteen songs) and 23 June (six songs). Both the cover of the home video release and McCartney himself in his intro to McCartney Years DVD acknowledge only the Seattle concert, however. These concerts were part of the 1975–76 Wings Over the World tour, which also produced the triple live album Wings over America (1976) and the Wings Over the World television documentary (1979).
