Here's a grand piece of history. In 1956 The Crickets were signed by Decca Records. Buddy clashed with the producers, who wanted to pigeonhole the group into a country-western sound. Without any fanfare the company refused to renew their contract, and on the last day of February 1957 Buddy placed this call to Paul Cohen of Decca.
A few things to note while listening: Buddy's obviously being given the run-around here. But throughout the six minute call he buries his temper and keeps his cool. He displays a very civil and courteous attitude, even when Cohen tactlessly tells him that if another record company wants to 'waste their money' on him, that was their problem.
Later that year Buddy was signed to another label willing to 'waste their money' on him. The Crickets released 'That'll Be the Day' and he was on his way to superstardom.
