"Joe and Paul"
         
Paul Kofsky opened his first clothing store in Brooklyn in 1912. He called 
  it Joe and Paul  inventing an imaginary cohort, Joe, because he thought 
  people would trust him more if they thought he had a partner. By the early '30s, 
  Kofsky, a dapper man with a penchant for paper neckties, held sway over a successful 
  chain, with new locations in Manhattan and the Bronx. Sartorial success aside, 
  Kofsky had a greater ambition: to rub shoulders with the Yiddish stars of the 
  day. 
He made his dream come true in 1936 by walking into WLTH's studio and hiring 
  the station's musical director, Yiddish theater composer Sholom Secunda, to 
  write a song advertising his store. As for the singing, Kofsky would handle 
  that himself. 
For the next decade, Kofsky spent most of his days shuttling between stations 
  to perform his jingle live on the air and to talk theater shop with his fellow 
  performers. The ad became more than ubiquitous; to many listeners, "Joe 
  and Paul" was Yiddish radio.
So it happened that a young comedian named Aaron Chwatt (who later became Red 
  Buttons) used "Joe and Paul" as the basis for an extended Borscht 
  Belt parody of Yiddish radio. His routine centered on the fictitious station 
  WBVD, whose programming consisted of commercials interrupted by more commercials, 
  each sillier than the last. For listeners of Yiddish radio, the send-up hit 
  home.
Called to service in World War Two, Red Buttons left the hugely successful 
  skit in the Catskills, where the Barton Brothers comedy team picked it up from 
  hotel staff who had learned it by heart. The Bartons recorded the bit in 1947 
  for the fledgling Apollo label and soon found themselves proud progenitors of 
  the biggest Yiddish party record ever. According to Eddie Barton, three-quarters 
  of a million records were sold in a span of a few months. The song was so popular 
  it spawned a Latin cover arranged by Tito Puente. 
Ironically, most people who bought the Barton Brothers' 78 rpm never heard 
  the original "Joe and Paul" jingle, which had always been confined 
  to the range of New York City radio waves. Kofsky, it can be assumed, did not 
  mind the additional exposure.
