The Jazz Record

I went to a record store the other day...

I told the owner I was looking to buy a jazz record, but that I'd like to have a listen to it first. "That's fine by me," he said, and began to play a record. However, all I could hear was this buzzing noise: "Buzzz Buzzzz Buzzzzz." "This doesn't sound like jazz, what is this?" I asked. "Oh! I'm sorry," he replied. "I must have put it on the Bee side."
