The Cavern Club

From February 9th, 1961 to August 3rd, 1963 The Beatles performed at the Cavern Club regularly. On August 22, 1962, Granada Television went down to record The Beatles after hearing many reports about them and recorded them singing "Some Other Guy". The audio is ok and you can't really hear Paul's vocals. They came back on September 5th, 1962 to record more audio. They recorded "Some Other Guy" and "Kansas City / Hey-Hey-Hey-Hey". Some more video exists of other songs and audio for b-roll clips and rehearsal tapes but majority is lost as some of the video is missing and audio. The quality was too low for broadcast but was eventually released after The Beatles got fame on Scene at 6:30, November 6th 1963. There is also some rehearsal songs that are on bootlegs like "I Saw her Standing There" and there might be more but lost due to time.
