The first day we busked in Manchester with the double bass, we broke £100. Part of the key to our financial success was having a “bottler” – someone who would walk around the crowd with a hat while the band were playing, ensuring that no pocket went unemptied. Legend has it that the word “bottler” came from a tradition whereby someone would go from table to table in pubs collecting money for the musicians, with a hat in one hand and a bottle in the other.
