Clint Howard sings 'The Old Man at the Mill' on 'The Original Folkways Recordings of Doc Watson and Clarence Ashley' Smithsonian/Folkways CD SF 40029/30 with lyrics almost identical to Dillard's version posted above. The raven verse is the same as that given by Dave except the raven says 'if I was a young man'. I thought that stanza had shades of 'Leather-winged Bat' - of which I am most familiar with John Koerner's version - and that was confirmed by the notes to the Smithsonian CD. Rinzler writes that the 'Old Man at the Mill':

... is a happy combination of two separate songs: a wellknown party piece 'The Jolly Miller', and 'The Bird Song' or 'The Leather-winged Bat'. An 1883 version of the former is reported by Newell (pp102-3) and both Botkin and Randolph include it in their collections. 'The Leather-winged Bat' can be found in Lomax's 'Folksong USA, and Sharp provides two modal tunes and humorous verses for 'The Bird Song' in the second volume of his 'English Folksongs in the Southern Appalacians'.
