Moanin' was a jazz instrumental written by Bobby Timmons (who also wrote Dat Dere) whilst in Art Blakey's band - it later had lyrics added, just like Work Song, Watermelon Man, Comin' Home Baby, etc
the Lulu Godrey is a great version, bought mine about 4 or 5 years ago and never seen one since. NY label, not the same Finch label as the Albert Washington 'Ramble' etc which is from Ohio
