first rock and roll concert at the Gardens was held in 1956, featuring Bill Haley & His Comets. Elvis Presley's shows at the Gardens on April 2, 1957, were his first-ever concerts outside the United States. The Gardens also hosted evangelist Billy Graham during his Canadian Crusade, in 1955. Smythe-Ballard-Bassett in partnership: 1961–1971 In 1961, Smythe sold most of his shares to a three-person partnership formed by his son, Stafford Smythe, with Harold Ballard and John Bassett. The new ownership added 962 new seats to the Gardens in 1962 and added a private club, The Hot Stove Club, the following year. Even more seats were added in 1965 and new mezzanine galleries were constructed in 1966 and 1967. By 1968, seating capacity for hockey had grown to 16,485. This was achieved, in part, by making the seats narrower, so that—in the words of founder Conn Smythe—"only a young man could sit in them and only a fat old rich man could afford them."

It was the only venue to host the group on each tour. In March 1966, Conn Smythe resigned from the board of directors after a Muhammad Ali boxing match was scheduled for the Gardens. He found Ali's comments about the Vietnam War to be offensive and said that by accepting the fight, Gardens owners had "put cash ahead of class." Also in 1966, a new centre-hung scoreboard with a digital clock was installed replacing the SporTimer which was an analog clock. One of the designers of the new scoreboard, Paul Morris, was by this time the arena's public address announcer, a job he would hold until the Leafs left the arena. Ballard and the younger Smythe
