The Osmonds released the “Crazy Horses” single from the L.P. of the same name in October of 1972. The tune was written about air pollution (crazy horses = cars) and it rose to #14 on the Billboard US Hot 100 and #2 in the UK.
I can remember the first time I heard this song. My buddy Curtiss had the L.P. and we went over his place to listen to it. It seemed wild with that Yamaha keyboard Theramin squeal going on and I liked it right away. This would have been a few years after the original release. Probably somewhere around 1975 or ’76. Enjoy the psychotic equines!
