The chart record of Wings, even stateside in the US, tells just how ambitious McCartney still was beyond his Beatles days. Wings and McCartney, in all their various name-shuffling, scored a total of 37 Top 40 single hits between 1971 and 1989. That's two more charting hits than the Bee Gees! And mind you, this was after all the Beatles' fame and success. Guinness Book of World Records has McCartney as "most successful composer and recording artist of all time."
Denny Laine, in his first vocal lead for Wings, had had a meandering career both before and after Wings, easily overshadowed by the McCartneys. However, he had been with Moody Blues, Trevor Burton, and Ginger Baker's Airforce, and would go on to many solo and guest stints afterwards. Hailing from Birmingham, he gave McCartney a spice never before experienced: a Mersey-beat meeting a Brum-beat.
