gigster

A horse that pulls a gig (a two-wheeled carriage).

A musician who plays gigs (shows).

Of additional interest to dance band musicians was the opening that month [November 1935] of an extension to Manchester’s largest musical instrument store, Mameloks on Oxford Road. The store had a ballroom, café, lounge, and teaching rooms. The Dance Band and Variety booking agencies on its premises made it a center for ‘gigsters’.

Regular gigsters say it's a good venue to play and the promoters have worked hard, even if they have to stuff three bands on a night to make ends meet.
