The following band's I have seen on their first U.S. tour's were Peter Green with Fleetwood Mac, Jethro Tull, Joe Cocker and his Grease Band, Led Zeppelin which still shakes me up today, Yes, and the Soft Machine. Which first tour Band's do you remember?

Everyone who played the San Diego Sports Arena, Golden Hall, the BUT or any other venue in the early 1970's.
Hendrix in '67 in Santa Barbara, Zep in '69 (my little band opened for them and technically it was the second part of their first tour) in Honolulu, Tull in '69...note that Tull and Zep made pretty much every other band (except Hendrix of course) seem like they were "loitering"...not my term but somebody in Rolling Stone back then said that...perfectly.
Me too seen Zep and Tull also Vanilla Fudge together, for 5.00.......What a trip///////////
Outsiders, Chad & Jeremy, Lovin' Spoonful, Casinos, Standells, McCoys, Strawberry Alarm Clock, Terry Reid, Blues Brothers.

Most of these were opening acts--it might not have been their first tour but likely was. Many were supporting their first hit single or LP.
