1938 seems to be a time of looking back. Begin the Beguine, Bei Mir Bist du Schejn, A Tisket A Tasket were older tunes that became big hits in '38 (1,2,3 spots on the chart) Bob Hope's THANKS for the MEMORIES would become his signature HIT and was new that year:
I love Begin the Beguine, and it was "old" when I was a little kid in the 50's. It's a genuine classic. And NO ONE played it better than Artie SHAW! It's a fantastic dance tune. So, though it was an earlier tune, Shaw's rendition from 1938 has a real timelessness about it.
