How precious that this footage exists. This is a 43 minute BBC performance from 1972 recorded in England. Since it's only four years after the band was conceived, the hard drug use I'm sure already existed but had not yet taken it's heavy toll. IMO one of the greatest vocal groups ever! No auto tune going on in 1972 folks.......

I saw them live about 1972 and there were three lead singers. All three sang lead on a few songs with the others singing back up is how I remember it.
Also remember the drummer was a black guy in red bibbed overalls and he was better than average.
I think the first couple of albums pictured all those guys on the cover, maybe 7 or 8 guys. But later only the three singers were pictured on the album covers.
I remember a lot of kids yelling for "Jeremiah Is A Bullfrog". I think that is actually a song called "Joy To The World".
Three Dog Night - one of the bright spots of 1970's AM radio ... before FM became standard in cars! Great mainstream music!
Three Dog Night was a "date up" band in college. If you usually were dating "8's'' and had two tickets to a TDN show, you were going with a "10."
