Before Gordon and Andy became 2/3 of the Police, they earned their money playing German prog rock with German classical music composer and director Eberhard Schoener (known from Jon Lord's Windows and Sarabande - which also featured Andy Summer - projects), Sting wasn't such an unbusy player back then:
Even as the Police they still made music with Schoener:
Schoener has claimed that it was him who encouraged Sting to sing more with his falsetto:

Nor are Herr Summers' abilities limited to strange Telecaster bar chords loaded with effects in mock reggae rhythms, he can play classical guitar adeptly as well, that's him here at 1.22:
It explains why initially the fashion- and trend-conscious English music press thought that a band consisting of a Deep Purple organist and Kevin Coyne sideman (Summers), a big band jazz bassist (Sting) and a prog rock drummer - Curved Air - whose brother managed Wishbone Ash (Copeland) weren't the most credible representatives of neo punk New Wave, dyed blond hair and boilersuits or not. They were perceived as old musos/wannabees (Sting!) hopping the new wave train. Kind of like Marcus Miller, Al di Meola and Lenny White getting together today and saying that they are now a grindcore band.
