Correct, Fountain & Azteco are helping us out by donating voucher cards that mean everyone that comes to the show has to download the fountain app to get their lightning wallet and then they can add £5 worth of bitcoin (about 6000 sats) to boost the artists. We will see how it works as I'm expecting the majority of the room to be music fans and not necessarily bitcoiners. Luckily, I run the Bitcoin Essex meetup and we have organised a meet up on the same night. I have plenty of our troops in the field to help normies with the process.
