The mid-1930s found Bing ,with Jimmy Dorsey perhaps in a parody of the old nursery rhyme 'THE HOUSE THAT JACK BUILT.The fine piece of  mid-tempo jazz ,also found Bing interested.A fab vocal!Was he refering to his mentor Jack Kapp?Speculation has it's limits? I ran across an old book by hollywood stuntman,Buster Wiles "My Days With Errol Flynn".While his only reference to Bing was his friendship with Wilma Wyatt (before) she was Dixie Lee,there is also  a reference to a PLACE called THE HOUSE THAT JACK BUILT..He does NOT name Bing nor  give a year, but this bar, near the Santa Anita Racetrack,did exist in the 1930s-1940s.Considering Bing's interests in racetracks, & in a bar  'watering-holes near them,it's good speculation that Bing could have paid a visit?Or a reason to record this  song title ?
