I have a recording of the 1934 recordings of The Sons of the Pioneers.
Cool Water is on this record as is Tumblin' Tumbleweeds. The harmoies are so tight and the recording was done in one take each time and the best take was chosen for the pressing. No Auto Tune for this Boy Band.

If Roy Roger, Bob Nolan, and Tim Spencer were the vocal heart of the band, Hugh and KLarl Farr were the musical heart. The Farr brothers on guitar and fiddle sound as good as Django Reinhardt and Stephane Grappelli. Under appreciated because it was just cowboy music. Listen close and this is some hot swing.
