"A ROUNDUP LULLABY," by Charles 'Badger' Clark has been shortened, revised, re-named and otherwise messed with, probably by scout and camp supervisors who couldn't recall the lyrics. The correct lyrics were posted by vrdpkr in thread 55580, 11 Jan 03, which I linked above (and here, again): Roundup Lullaby
No one seems able to give citations for the error-ridden and/or changling versions quoted here (I hesitate to call them 'folk' since the poem is 20th c.: 1915, from "Sun and Saddle Leather," copyright Clark), and more keep surfacing. Certainly they are not by Clark. Nowhere did he use the line or title 'desert silvery blue beneath the pale moonlight (starshine)'. The first four lines of the first verse are "Desert blue and silver in the still moonshine, Coyote yappin' lazy on the hill, Sleepy winks of lightnin' (not light) down the far sky line, Time for millin' cattle to be still."
Some six musical settings by different composers had appeared by 1952, according to a forward by Clark to an edition of "Sun and Saddle leather" published that year (Chapman and Grimes, Boston), which was enlarged to include further published collections of his poetry; "Grass Grown Trails," and "New Poems." Some musical settings may be responsible (The one by Clifton Barnes, cited above by Tinker, which includes two verses and the first chorus by Clark, is an honest shortening of a poem that may have been too long to fit on the old 78).
Whose tune was used for the midi given in the link at the top of this thread is not stated. It is as dull as can be. There should a change in melody for the five lines with changed meter which end each verse.
