Rock and roll has usually been seen as a combination of rhythm and blues and country music, a fusion particularly evident in 1950s rockabilly. There has also been cross-pollination throughout the history of both genres; however, the term “country-rock” is used generally to refer to the wave of rock musicians of the late 1960s and early 1970s who began recording rock songs with country themes, vocal styles, and additional instrumentation, most characteristically pedal steel guitars. John Einarson states, that "[f]rom a variety of perspectives and motivations, these musicians either played rock & roll attitude, or added a country feel to rock, or folk, or bluegrass, there was no formula".
1958 saw its first Canadian rock and roll teen idol Paul Anka, who went to New York City where he auditioned for ABC with the song "Diana". This song brought Anka instant stardom as it reached number one on the US Billboard charts. "Diana" has gone on to be one of the best selling 45s in music history. US-born rockabilly pioneer Ronnie Hawkins moved to Canada in 1958, where he became a key player in the Canadian blues and rock scene. The 4th of October was declared "Ronnie Hawkins Day" by the city of Toronto when Hawkins was inducted into Canada's Walk of Fame. He was also inducted into the Canadian Music Industry Hall of Fame and his pioneering contribution to rockabilly has been recognized with induction into the Rockabilly Hall of Fame. https://www.youtube.com/watch?v=gtKVuwDQUl0
