I consider myself a drummer before anything else, but out of necessity I've learned how to get on without one. If you dudes can stay in time you may not *need* one. I saw an earlier post about some older country stuff not allowing a drummer. I'd agree. You don't. But you better know how to do his/her job too. Smack your guitar or bass, stomp a foot when the song needs it. There's an old joke about drummers...
Why do drummers put drumsticks on the dash of their car?
So they can park in the handicapped spot.
It's a lonely road...
