Elvis Presley, The King of Rock and Roll, was told to stick to driving a truck because, he was told, "you will never make it as a singer".
Before he was the legend he is now, Elvis Presley was just another boy with big dreams to be a singer. Along with his many attempts at landing a professional, he worked as a truck driver. During this time, he met a fellow musician, Ronnie Smith, with whom he had worked briefly before, and who was a member of a professional band at 16.
He put Elvis in touch with the band's lead Eddie Bond, who was looking for a singer; Elvis was asked to audition, and he turned up at a club called the Hi Hat, where he performed a couple of songs for Eddie onstage. He was turned down, with Eddie claiming that Elvis will "never make it as a singer", and that he should just stick to driving a truck. Later, Eddie claimed that he was asked by the club to reject Elvis.
A few months after this debacle, Elvis recorded "That's All Right" for Sun Records – a song that became a massive hit in Memphis. Eddie Bond got then got Ronnie to ask Elvis whether he would be interested to sing with them – an offer that Elvis politely refused.
