Boyse was an avid jazz pianist. He was constantly invited to the 'Boston States' to play, but never ventured far from Africville. He played with Benny Jones (trumpet) and Earnie Dixon (sax) at the local hall.
If you heard Boyse finish a song and say out "I'll be right back," you knew he wouldn't be and he was done.
His band was accompanied by three sisters (Aunt Midi, Aunt Knewly, Aunt Nucky) who had unmatched harmonies. However if they were out of tune, Boyse would stop playing, stop the band and let them know that they were "singing it wrong."
