This is Chattanooga Choo Choo. I found this recording off of an old "Alpha Beta" market record that contains a compilation of Big Band hits. This features Tex Beneke & The Modernaires. The recording quality is excellent and the performance is amazing. It was also done in true stereo so I'm suspicious of it being an early recording as the record sleeve suggests. I don't know what album this came off of originally so let me know if you have any info on this particular track.
