response: I know that in 1951 Cleveland Disk-Jockey Alan Freed began playing some music using the term ''rock and roll''.
history: Ive been listening to a lot of rock and roll lately. So you probably know that rock and roll emerged as a defined musical style in the United States in the early to mid 1950s. I thought it would have been the UK. That is really cool. It seem it derived most directly from the rythm and blues music on the 1940s.  Do you like any particular singer? I like The Rolling Stones. They are really good. Oh do you!   That band was formed in 1962, in London England. There has been some great rock and roll coming out of the UK. What else can you tell me about the origins?
knowledge: In 1951, Cleveland-based disc jockey Alan Freed began playing this music style while popularizing the term ''rock and roll'' to describe it.
