Walker's music career began at the age of 12, performing at local venues until 1953, when he began to appear as part of the Radio Rangers on CJFX Radio. After 1956, he appeared as part of the West Virginia Jamboree Show with Charley Bailey and later toured with future Canadian Country Music Hall of Fame alumni Fred McKenna and George Beck. Walker joined Vic Mullen, Brent Williams and Harry Cromwell and became one of the earliest performers of Canadian Bluegrass music in the early 1960's. After disbanding in 1961, Walker worked with Mac Wiseman and made appearances with Doc Williams and The Border Riders with "The Countrymen" who consisted of Walker, Beck, Mullen, Chuck Lohnes and Ross Broughm. The group also had a radio show for CJCH in Halifax before later uniting with Williams and Cromwell as part of Beck's "Maritime Playboys" on a weekly TV show for CHAU in Carleton, Quebec. Later, Walker joined Dougal Trineer, Paul Menard and June Davey as The Hackamores in the Montreal area, gaining "much recognition as an up and coming country singer." Four of Walker's singles charted above the top 50 in RPM Magazine's weekly ranking of Country music songs between 1965 and 1971. Cadillacin' Around, written by Will Odo and recorded with The Hackamores, plateaued at #2 and gained him "national popularity" before winning the RPM Gold Leaf Award for "Most Promising Male Country Singer" in 1965. Peaking at #35 in 1970 was Crazy Tricks, written by Merv Smith and produced by Dick Damron and recorded in Edmonton during a time where Walker continued to have popularity in Quebec and the Atlantic provinces. In 1971, two of Walker's recordings reached the top 50 starting with the self-penned Canadian Country Music Man featuring Marie Babin and "first call" studio lead guitarist Mickey McGivern, reached as high as #22 and Parliament Hill, written by Ben Kerr, peaked at #18 on RPM Weekly's Country song listing. In the fall and winter of 1970 and 1971, Walker made appearances on CBC's Countrytime with the moniker of Canada's Prime Minister of Country Music. On May 12th, 1971 Walker joined notable folk performer and television personality Don Messer on a tour across Canada. Walker also spent time playing at clubs in Hawaii, starting in 1972 in addition to performing Parliament Hill on an episode of The Don Messer Show that aired on January 29th, 1972 on CJAY-TV. In 1975, he received "heavy east coast airplay for his Diesel Drivin' Man single" recorded with his band The Cabinet featuring Steve Lau and brothers, Larry and Henry Brennan. Walker began on an indefinite hiatus from his music career due to medical issues in 1977.
