クオリーメン
Pete Best was studying at the Collegiate Grammar School when he decided he wanted to be in a music group, so Mona bought him a drum kit from Blacklers music store and Best formed his own band; The Black Jacks, who later played in the Casbah. Chas Newby joined the group, as did Ken Brown, but only after he had left The Quarrymen. The reason for Brown's exit from the group was that he turned up on the seventh Saturday night of The Quarrymen residency at the Casbah with the flu, so Mona ordered him upstairs to the Best's living room to rest. This caused a massive quarrel with the rest of the group when Mona came to pay them, as they wanted Brown's money to be shared amongst the three of them, as Brown had not played. Mona refused, so The Quarrymen angrily cancelled their residency and stormed out.
