It's nostalgia central at the Southbank Centre right now, with the windows of the Festival Hall festooned with neon artworks by the late Chris Bracey - designer and founder of Walthamstow's neon signage treasure trove, 'God's Own Junkyard.'
After growing up in a family that made its living designing and manufacturing signs for fairgrounds, Chris left home to became a 'proper' graphic designer, only to find the pull of neon - or 'liquid fire' as it's known in the trade - was too strong.
1970s Soho needed his talents and was happy to pay for them. Bracey's subsequent fabulously tawdry output there even included the infamous 'Girls Girls Girls' that adorns Raymond's Revue Bar.
Seeing some of Chris's neon work in a high-art context - and with Tracey Emin a regular neon-user these days - made me think about why its appeal is so enduring.
It's attention-grabbing, tacky and cheap and it offers the same cheap-thrill instant gratification as a ride on the dodgems or the taste of candy floss.
Neon says the good times might not be classy, but they'll sure as hell be fun.
