I don't know that detail but his first RCA single became the top hit in the US.
There have been conflicting reports.  His first single in 1956 was Heartbreak Hotel
Hi, I love Elvis Presley. How about you? Not one here but what year did you become his fan? He begun his music career during 1954. I can't really remember, I've just been a fan of his music for a long time. It's a shame he passed so early, do you know what year that was? Well he died in August of 1977, he was just 42 since he was born in January 1935. That's short lived, how many albums did he release during that time? I don't know be he is regarded as one of the 1900's most important cultural icons. How did he die?
Presley's first RCA single, ''Heartbreak Hotel'', was released in January 1956 and became a number one hit in the United States.
