Fleetwood Mac - Live USA (Live & Alive) from 1969?

[kowk]

Hi, I need some help :-).
I'm going to buy this CD http://www.fleetwoodmac.net/penguin/albums/liveusa.htm
There is a description : Recorded live at the "Tea Party Club" in Boston, MA, USA in 1969.
Is it true the recordings were made on the first FM visit (Nov. 26 - Nov. 29. 1969) in Boston on the third tour of th USA?
I know that 3CD "Live in Boston" was recorded on their second visit to Boston the same tour (February 1970). I have these CDs :-).
Regards
