If you used Clearing in 2024, how did you find it?

Alexandria Palace London Concert Age

Beabadoobee will be doing a Concert in alexandria Palace in London and I was planning to buy the tickets this Friday but when I looked at their website it said it is only 16+.
Im only 15 but my friend will be 16 before the concert. Do you think they would let me in? Or would they even Age check?
When I went to troxy for a concert once, they explicitly told us to get our passports ready so it can be checked but once the line started moving to go on they didn't Age check anyone!
I really want to go but I'm obviously not 16!!
