What do I say to my crush on a first date when I see him?

He will play at a concert that night he's helping out another band. I'm horrible at conversation especially small talk

There will be obviously other people around at the bar and it will be loud also.

I will probably see him before he plays on stage. What do I say to him then? If I could I'd like to have a step by step tutorial yes haha

Like obviously Hi how are you probably but what then. I have no idea I've also never done anything else than hookups yes I know tragic. Help please
