The Folksmen were a fictional folk trio from the film A Mighty Wind (2003). They were a parody of popular folk combos of the early 1960s such as The Kingston Trio and The Brothers Four.
These are photos from concerts where The Folksmen played, so they may be of other bands that played the concert as well.
