Assistance With The Identification of an Older Tune

Partial lyrics are as follows ....All of the ladies attending the ball...(a reference is made to a person I believe to be a band member named Dash)......chorus follows with... You must change parters, you must change partners, again. This song has a lot of pedal steel guitar in it as well.

This song sounds very much like Crosby, Stills, Nash, and Young or even Buffalo Springfield. However, I can't find the the title nor the band name, Please Help.

Hi!

I believe it's called "Change Partners" by Stephen Stills
