Unless Don had a laparoscope appendectomy procedure he will most likely be unable to fulfill his gig schedule for at least 2 to 3 weeks. The most important thing is to make sure no infection occurs and to get complete rest for a speedy recovery of course.
Glad you caught it time Don.

A ruptured appendix would have complicated matters a little, to say the least.

Rest up and get well soon.

Oh, and try and keep your hands off those pretty nurses okay?

>> Just kidding.

All the best,
