I'll Get By (As Long As I Have You)
Ipana Troubadours; Bing Crosby, vocal                                 1929
         Ipana was the name of a popular brand of toothpaste.  The Troubadours were, in fact, the Sam Lanin Orchestra.  The use of recording pseudonyms was extremely common at the time - Lanin's band recorded under dozens of names. This was made before Crosby achieved stardom. He is not even given credit on the label, which merely states that the record features a "vocal refrain."
