Around 1952, Jack began to rediscover his love of the violin. He took his practicing seriously this time, working for hours in the bathroom adjoining his bedroom. He began giving benefit concerts with a combination of monologue and serious concert work, starting with the Los Angeles Philharmonic. Jack had long made comedy of his mediocre violin playing, but he was now playing Mendelssohn and Rimsky-Korsakov as opposed to "The Glow Worm" and "Love in Bloom". Isaac Stern became his informal manager, connecting symphony orchestras with him. When Jack once wondered aloud at why a symphony orchestra would want to hire him over Isaac Stern, Stern replied, "We real important violinists can only get $5.50 a ticket--but somebody as rotten as you--for you, they can charge a hundred dollars a ticket!" Jack also had a running joke that at most concerts, the expensive seats are down front. In his, the cheap seats were down front, and got more expensive the further away you sat. "For $200, you don't have to come at all!"
