It’s amazing! If you ever get the chance to do it, I’d definitely go for it!
So the PRK that I go to (or used to go to, as they no longer do a regular monthly slot like they used to) was in Islington. Some people that I know used to work for a radio station (Xfm), and it was part of one of their indie nights in London. The band get up on stage, and can play a huge range of songs. You sign up to the song that you want to go, and they call you up one by one to rock out to your fave songs!
My standard songs were Blondie’s One Way Of Another, The Undertones’ Teenage Kicks, and a weird punk-rock version of Kylie’s Can’t Get You Outta My Head, ha ha!
Where abouts is your school? Was it London, or Skelmersdale, or am I thinking of another one? If London, there are loads of places like Lucky Voice or Bloomsbury Bowling Lanes that let you hire out a karaoke booth, and they have a pretty good range of songs, so everyone’s happy, whether they like pop, rock, R&B or hip hop. When we’ve been before, we’ve even had people rapping!
