It's unclear to me if episode 2.8 was ever released (but the good quality of the video below seems to indicate it).
Season 2, episode 8 (Dec. 1, 1970):
1981 - Take These Chains From My Heart:
|Ray Charles and Buck Owens (clipping from Jet, 22 January 1981).|
|Buck Owens and Ray Charles on the cover of Song Hits (Jan. 1971).|
