Bandleader, arranger, conductor, record producer and trumpeter Joseph J. Leahy was a native of Boston, Massachusetts. He joined the Les Brown Band of Renown at twenty, then the Charlie Barnet band and later the Artie Shaw band, eventually forming his own orchestra for cross-country tours of ballrooms, hotel circuits, college proms and one-nighters.
Joining the United States Army in 1941, he headed the forty-man Army Air Force Orchestra of the Air Transport Command, for which he wrote all the arrangements. The orchestra gave weekly broadcasts over CBS.
His other Air Force duties included arranging and conducting for variety shows, half-hour transcriptions, cue music and orchestral works, and a two-year world tour arranging and conducting for troop shows.
Upon leaving the service in 1945 he came to New York and signed with CBS as a staff conductor-arranger, doing script-show music, background music for radio dramas, and conducting the Skitch Henderson orchestra. Just over a year later he began doing freelance arranging and conducting, and for six years thereafter he orchestrated over one hundred radio programs including the longstanding Don McNeil's The Breakfast Club in Chicago, Illinois.
Other radio and television shows for which he did uncredited background music included those for Orson Welles, Rita Hayworth Eddie Cantor, Tony Martin, Ethel Waters, Constance Bennett and many others.
By 1954, Joe Leahy moved into the record industry by forming his own label, Majar Records, which had an immediate hit: "If I Give My Heart to You" (Majar 27), arranged and conducted by Leahy and sung by Denise Lor. The tune inspired eighteen other cover versions.
Leahy followed up with "Unsuspecting Heart", sung by Terri Stevens; "Green Fire", the song from Desiree, and then he introduced "How Important Can It Be" with Jack Smith.
In 1955 he joined the RKO Unique record label based at 1440 Broadway in New York, which soon had a top-ten hit with "The Man in a Raincoat" sung by Priscilla Wright in her first recording. Joe Leahy's first album was Lovely Lady (LP-106) for RKO Unique.
Though Joe Leahy's music has been nearly forgotten in the 21st century, many of Joe Leahy's albums have recently been re-released on compact discs.
