NEMS had a staff of twenty-five at the time of its move from Liverpool to London in 1964. NEMS booked the Beatles' concerts, and it also presented groups as an opening act. It accrued money as promoter, booking agent, and manager for all concerts. The Beatles were constantly in demand by concert promoters, and Epstein took advantage of the situation to avoid paying some taxes by accepting "hidden" fees on the night of a performance, which he always kept in a brown paper bag.
