found: Jascha Heifetz WWW site, January 6, 2014(His original compositions were limited to popular songs written under the pseudonym Jim Hoyl. One, "When you make love to me (don't make believe)," became a hit in 1946. Once the song had made it on its own, Heifetz confessed to writing it. Over the years, Jim Hoyl became something of an alter ego to Jascha Heifetz. "Jim Hoyl" became the antithesis of "Jascha Heifetz": relaxed, anonymous, Tin Pan Alley. Heifetz's fishing licenses bear the name Jim Hoyl, and at parties he asked others to call him Jim.)
