The groups first tour, in 1969, had a new-day spirit and a set list all its own.

But the future, more than the past, permeates the album.

(Alas, another song from Youngs Springfield days, Broken Arrow, didnt make the cut.)

Its great to hear Crosby and Nash and Stills, he said.

I had just joined the band like within weeks of when that happened.

It was like two weeks after Woodstock or something.

Its a pretty cool record.

But in September 1969, all that music and turmoil remained far on the horizon.

Looking back on those Fillmore shows, Stills says, in a statement, We just went for it.

What we lacked in finesse, we made up for in enthusiasm…A band on the run.
