The Stranglers played the Folkestone this day in 1993. Not sure where I got this from but it was on an earlier version of the Folkestone Gerald. I did not attend.
Other gigs at Leas Cliff Hall I have been to are Robert Plant / Saving Grace at Leas Cliff Hall (2022), Billy Bragg (2021), Squeeze at Folkestone Leas Cliff Hall (2019), The Darkness (2013), Ozzy Osbourne in Folkestone (2010), Editors ('10), Frank Skinner ('07), The Dirty Pretty Things (2006), The Mighty Boosh ('06), The Darkness (2004)
It's on The Leas, overlooking the channel, though you'd not realise that when you're inside at a gig.
