When I was older, the best times during the summer were to do with playing music, and hanging out with other bands...
we played at this one day festival in Brighton, and a few other bands we knew from our home town were alos on the bill, that was a great two days, the venue was right across the road from the beach, so we played football on the beach, and got drunk on coca cola flavoured booze.
also, i spent 3 days travelling around London in the back of an old ambulance with a couple of bands, as they went off to do gigs, and a peel session for the the radio.
That was an interesting adventure, haha, we went to this crazy party in the underground of a house, and I have no idea how my friend and I negotiated the London underground lines to meet someone off the bus, given the altered state of mind we were in.
I stayed on in London after that weekend, stayed with my older bro, and picked up the first pressed copies of the CD album our band had 4 songs on from the record company. that was a great summer trip all round.
Not the usual kind of summer holiday i guess, one that money can't buy.
