Music will be a large part of the weekend. With a majority of guests musically inclined, there will be many a jam session around the campfire. Below is a list of songs that are very likely to be played more than once. If you feel like jamming and singing along, give them a listen. You might discover some new music that you love.
On a side note, if some of these songs aren't your thing, learn them anyway! This is about having fun. Yes, some songs may be cheesy, but these are songs that lots of people will know and have a blast singing. Losen up and enjoy it. Sing! You'll feel better, I promise!
The Band - The Night They Drove Old Dixie Down (obviously the version from The Last Waltz)
