Whenever I'm calling at a local country dance club I take along:
   1. Amp
   2. Speakers
   3. Stands
   4. CD player
   5. Case of CDs
   6. MD player
   7. Case of MDs
   8. Case of index cards and books with calls
   9. Radio mike
10. Fancy waistcoat

I could make life a lot easier replacing items 4 to 8 with one laptop.

But probably won't. Eggs, basket.
