Around April 1965, he changed the spelling of his surname from Loughran to Lockran for stage purposes. His British live schedule at this time included a package tour called 'Kings of the Blues' with Long John Baldry, Alexis Korner and Duffy Power. On 6 August 1965, Lockran, together with Aungier and Rivers, founded 'Folksville', a folk and blues club at the Half Moon, Putney in west London which remains a thriving music venue. In 1966, Lockran secured a recording contract which resulted in the release of his first album "Hold On - I'm Coming!", featuring Danny Thompson, Terry Cox and Ray Warleigh. He followed this release with "Blues Vendetta" in 1967, featuring "Jason's Blues", written for his three-year-old son. In 1969, "The Essential Gerry Lockran" was released, and he also featured on the "Blues at Sunrise" compilation album with Redd Sullivan, and Dave Travis. In the early 1970s, his career was managed by Nigel Thomas, who also represented Joe Cocker, The Grease Band, Faces, Chris Stainton and Juicy Lucy. During 1972 and 1973, Lockran toured the U.S., Canada and Europe as part of package of tours featuring these artists. The U.S. and Canadian tour headlined by Joe Cocker lasted three months, and involved 40 concerts at venues including Madison Square Garden in New York and The Forum in Los Angeles. This was followed by a two-month European tour through France, Holland, Italy, Germany and England. Lockran recorded further albums during this period, "Wun" (released in 1972),"Pinup" (released 1973) with Henry McCulloch, Neil Hubbard and others,then "Rags to Gladrags" (released in 1976) with musicians including Ronnie Wood, Mick Ralphs, Henry McCulloch, Neil Hubbard, Alan Spenner, Philip Chen, Pete Wingfield, Mel Collins, Bruce Rowland and Cliff Aungier. He then concentrated on touring in Europe, performing in Germany, Austria, Denmark, Holland, Belgium, Switzerland, France and Italy, working with blues harmonica players Matt Walsh and Walter Liniger, Hans Theessink and Ian Hunt, with whom he recorded "The Shattered Eye" (1979) and "Total" (1980). Around this time he also started to use the relatively new Ovation Legend guitar. During a tour of Belgium and Holland in 1981, he started suffering heart problems, which culminated in a heart attack and stroke, depriving him of the use of his left hand and effectively ending his career as a professional musician.
