Ultimate Classic Rock heeft een overzicht van albums die onder verschillende titels uitgebracht werden. Zo ook “A Quick One”, dat in Amerika uitgebracht werd onder de naam “Happy Jack”.
“Both the Beatles and Rolling Stones had their ’60s U.K. albums consistently tinkered with — alternate track-listings, weird repackages, etc. — prior to release in America, but neither had a long-player renamed while retaining virtually the very same cover art and songs, as did the Who with their sophomore opus. Released as ‘A Quick One’ in their homeland, the American version removed their cover of the Martha and the Vandellas hit, ‘Heat Wave,’ and added the single, ‘Happy Jack,’ for which the U.S. LP was named“.
