If you were up late last night, you might have notice a familiar phrase on a t-shirt worn by one of the musical guests on NBC’s Late Night with Jimmy Fallon. Lead singer J. Robbins is the guitarist and lead singer of Jawbox, which made its first appearance since 1997 during the show. Robbins’ was front and center, wearing a Fight SMA t-shirt! His son, Callum, has spinal muscular atrophy, and in the past few years J. has become a great voice in the SMA community.
