Nick has also had a relatively lengthy career in music. Early on, he was a member of The American Dream, a 1960s Philadelphia band whose debut album was Todd Rundgren's first production credit. More prominent success soon followed when he briefly became the unofficial fourth member of the British blues-rock band Foghat in the mid-1970s, producing several of their albums as well, including Fool for the City, which spawned the band's biggest hit "Slow Ride." Nick's bass-playing is prominently featured on this track as well as the rest of the album. He has also released a couple of solo albums: Already Free (1977) and A Crowd of One (1986), the latter of which featured the single "Weatherman," which cracked the Billboard Hot 100. The track has a breezy pop-rock feel that was fairly typical of the mid-'80s. It is somewhat similar in terms of both melody and tempo to Mr. Mister's big hit, "Kyrie," albeit with much lighter percussion. A year later, Jack Wagner recorded a cover version of the tune (under the title "Weatherman Says"). Another track from the A Crowd of One album, "Love's Closing In" was also featured on the soundtrack to the 1986 film, A Fine Mess.
Although a United States native, Jameson has become very well-known for his ability to perform in a variety of deceptively authentic accents, particularly British English and Australian.
