Starship (formerly Jefferson Starship) rebooted and released "Knee Deep in the Hoopla" in 1985. The first single was the bouncy "We Built This City", with co-lead singers Mickey Thomas & Grace Slick alternating on vocals. As for the DJ heard in the bridge? Former DJ Les Garland, at the time an executive with MTV, lent his past expertise in a brief vocal cameo.
Even though Garland clearly referenced San Francisco, Starship's home base, the phrase "city that never sleeps" is, of course, more commonly associated with New York City, MTV's base. Go figure.
