I know they played Winterland (with the Guess Who, Chambers Bros and Mason Proffit),  and at Atlanta Pop in 1970, I have the pictures to prove it!! They also were the house band at Whiskey A Go Go back around 1970. Great band...What I am looking for is live recordings of the band.

They played the Fillmore on 12/18 & 12/19 1970. The lineup was Jo Mama, Gypsy, Poco, & Savoy Brown. I remember none of us ever heard of them but they  blew us away. As usual Bill Graham brought a strange mix of artists together. Me & my friends were hard core blues rock fans but came away Poco & Gypsy fans.

I attended a show that weekend as well. Gypsy was terrific. I ran out to buy their double album the next day. That was also the night I discovered Poco, my favorite band of all time.
