Don't know if this counts, but my mother worked at the local cinema as the book-keeper. As TV started to take a hold in the late 50's the cinema occasionally held live concerts - I managed to sneak in about 15 minutes of one with Lonnie Donegan and Tommy Steele once.
I was only about 9 or 10, and I think it must have put me off for a while as the next event wasn't until I was 16 and riding around on a chrome-bubbled
Vespa 160GS (picture not of mine, sadly - used to have a pic, but think it went the way of many that my parents had when they had the odd clearout), and was the original Moody Blues with singer Denny Laine in Balham South London (still have the 45 rpm record 'Go Now' up in the loft somewhere...)
