Gil Mellé was another who did a swing version of the Rozsa theme. It's on the "Complete Blue Note '50s Sessions." Two of my favourite musical figures in history, together! But I can't say it's a piece that really lends itself to that treatment. I've filed it in my brain under "interesting".
I just don't think this is a great choice for a swing number.
I wouldn't write it off as just "interesting," though I admit I have a soft spot for interesting recordings. I really don't think this falls too far away from the same tree from which "Laura" or "Stella by Starlight" fell.
When you commission lyrics to be written for your love theme, you sort of make it fair game, right? This isn't as awkward an example as "A Star Beyond Time," is it?
