This is an interesting version of Friday Night Fish Fry. It is not the original recording. The person who posted it admits that it is an unreleased version. What we call a rare live recording in the collecting business. This version swings a lot better than the original. It is also in Stereo, which makes me think that it might be a latter reissue. Some artists from the swing era would re-record their hits with the advance of technology, or the record company would electronically change the recording to stereo. However listening to it closely I am pretty sure it is re-recording.
