There have been several versions of this concert released as bootlegs.
Whilst I have not received a copy of the CD yet to confirm the concert is accepted as ‘essential for the Jackson Browne fan.The concert was recorded at The Main Point, Brym Mawr, PA on the 7th September 1975.
The show was broadcast on station WMMR-FM and of course many people taped it! Hence the plethora of bootleg CDs released.
The show was for a series of benefits and therefore was advert free!
Because of the long length the ‘taper’ had to turn the tape over or switch and there was a slight delay between “Son For Adam” and “Cocaine” but of course different sources may have resolved this.
From my research when Runaway was finished the poor DJ on WMMR-FM thought the concert was over and started his closing the show spiel.But then there was an encore!.Other bootlegs spliced alternative sources for the final track.
