When bands started to use their own P A s it became more expensive and unaffordable for any newcomers to get started (exept for the few spoilt ones whose family were on a high income) as equipment has always been too overpriced.
I can just remember back in 1961-62 seeing a local Cliff & The Shadows type band and there was only one mic for the lead singer and it was plugged into a separate combo amp beside him at the front of the stage. Don't know what it was but it probably wasn't very powerful for that period.
It was easier to get started back then as no one else had masses of equipment either.
I saw Cliff & The Shadows in March 1965 at the London Paladium in 'Alladdin' and we were 3 boxes up at the front on the left of the stage (only seats available due to cancellations) and I could hear the sound of Brian's drums & cymbals first hand almost below us and not miked. Also the three AC30s were not miked either and Cliff, Hank & Bruce were using the house mics that used to rise up and down at the front of the stage.
The sound being basic that way made it really 'live' and to hear it all accurately you could always play the records any other time.
