Background: Robertson was born Jaime Royal Robertson on July 5, 1943. He was an only child. His mother was Rose Marie Chrysler, a Cayuga and Mohawk woman who was raised on the Six Nations Reserve southwest of Toronto, Ontario. Chrysler lived with an aunt in the Cabbagetown neighborhood, and worked at a jewelry plating factory.
Context: The Hawks left Ronnie Hawkins at the beginning of 1964 to go on their own. The members of The Hawks were losing interest in playing in the rockabilly style in favor of playing blues and soul music. In early 1964, the group approached agent Harold Kudlets about representing them, which he agreed to do, booking them a years' worth of shows in the same circuits as they had been in before with Ronnie Hawkins. Originally dubbed The Levon Helm Sextet, the group included all of the future members of The Band, plus Jerry Penfound on saxophone and Bob Bruno on vocals.  Bruno left in May 1964, and at that time the group changed their name to Levon and the Hawks. Penfound stayed with the group until 1965. Kudlets kept the group busy performing throughout 1964 and into 1965, finally booking them into two lengthy summer engagements at the popular nightclub Tony Mart's in Somers Point, New Jersey, where they played six nights a week alongside Conway Twitty and other acts.  The members of Levon and the Hawks befriended blues artist John P. Hammond while he was performing in Toronto in 1964. Later in the year, the group agreed to work on Hammond's album So Many Roads (released in 1965) at the same time that they were playing The Peppermint Lounge in New York City. Robertson played guitar throughout the album, and was billed "Jaime R. Robertson" in the album's credits.  Levon and the Hawks cut a single "Uh Uh Uh" b/w "Leave Me Alone" under the name The Canadian Squires in March 1965. Both songs were written by Robertson. The single was recorded in New York and released on Apex Records in the United States and on Ware Records in Canada. As Levon and The Hawks, the group cut an afternoon session for Atco Records later in 1965, which yielded two singles, "The Stones That I Throw" b/w "He Don't Love You" (Atco 6383) and "Go, Go, Liza Jane" b/w "He Don't Love You" (Atco 6625). Robertson also wrote all three of the tracks on Levon and the Hawks' Atco singles.
