The earliest commonly circulating Zeppelin live recording starts out immediately with 'Train Kept a Rollin' missing the first few seconds of music.
Recorded on a single 60 minute cassette tape. Extremely Distorted and muddy. The vocals sound a bit distant. The tape is listenable, but overall pretty poor.
The taper turns off the recorder after 'Dazed and Confused' and starts it up again presumabely only a few seconds into 'White Summer' although there is no way to tell how much music was missed.
'Pat's Delight' fades out at the end and cuts before it is finished. There was probably at least one more song performed that wasn't captured by the taper as finishing the set with a drum solo would have been strange.
