[on recording trouble with wax cylinders, around 1921] The tuba player and myself had to sit way back in the studio because when you blow notes out of the tuba it's too loud - the needle would jump off the cylinder and they'd have to start all over again. Same with the banjo. So I brought up the idea one morning of bringing my guitar to the studio and Sam [Lanin] put me under the horn. Visualize the great big horn and dog you see advertised by the Victor phonograph company; well that's what we had. That was the beginning of my playing guitar on record dates.
