Hmmm good little nostalgic prompt there. There are a lot of things that remind me of my childhood and when I specify it into just sounds there still remains a big enough list. The sound of some cartoons remind me of my childhood, just the theme. Also tv shows themes like the A-Team, Remington Steele, The Jeffersons, Misfits Of Science, the original BSG & V. Very nostalgic indeed.
I also would put in the sounds of the waves lashing against the beach shore, the sound of popcorn popping, the ringing of bicycle bells, the sounds from the schools & children laughing and talking. The sounds of sports games being played – footballs kicked around and into nets, basketballs bouncing on the court and the ‘plop’ as they are tossed into the net of the hoop, the sound of tennis balls being hit by rackets and badminton shuttle cocks being hit by badminton rackets, and the yelling of hide n’seek shrills as the kids play!
