Between 1932 and 1947 or thereabouts, but it wasn't a single continuous run. He started on CBS and moved to other networks later. The format varied too, generally about 15 minutes of song and a few chatty anecdotes and links, with later shows being put together by local stations from supplied discs of new recordings. Some DJs just used them as a source of songs to play, rather than as part of a Cliff-focussed show. He had a TV show too, about which I know fairly little.

I love the confidence of the opening lines.

Not sure I could have handled the state of dentistry.

Absolutely. An innate musicality, unique ukulele style and that three octave range. Few performers could switch so convincingly between novelty numbers and emotional crooning.

Right? And this one's actually good! :D

You're most welcome.

Thank you for commenting; I'm delighted that you enjoyed the song. I only have limited information for this material, but the artist is listed alongside the title (it is indeed Cliff Edwards) and the composers and year are in the description. Where possible I note whether it was a recording made for one of Cliff's radio shows etc.

Delighted to hear that you enjoyed it.
