Derek McGregor's definitions

45's

refer to single songs pressed onto a vinyl disc. The number 45 represents the rpm (revolutions per minute) that the vinyl needs to be played at, with standard size LPs requiring 33 1/3 rpm. Though they are called singles, they can hold roughly ten minutes worth of music between both sides.
