Hey [Friend's Name],

Quick update - I won a ticket to a music festival, and I think it would be awesome if you could come along.

I snagged it by nailing a music trivia question in a radio contest, and the festival is happening on the weekend of June 24th. I'm already getting into the groove by checking out the lineup and sorting out festival essentials. Let me know if you're in for this music-filled adventure!

Cheers,

[Your Name]
