According to his official website, former Grand Funk Railroad guitarist and vocalist Mark Farner is recovering from surgery. Farner, age 64, had a pacemaker put in earlier this week and is now back home resting.

Here is the official word from Mark and his wife, Lesia:

Hello everyone...we're back home now and settled in.  Mark is doing well. He's very  sore and has had the wind knocked out of his sails temporarily.  Doc said don't baby him so he's been up and around a bit. He was outdoors for a awhile yesterday just putting around, in the barn with his buddies Sylvester & LD the cats.  Today he repaired Jesse's over head lift and rested quit a bit. He's a trooper!  Jes was so happy to have the lift fixed as were we all and Mark said it made him happy to be able to fix it.  He's making a lot of effort to not let the stiffness set in so he doesn't  loose range of motion.  So he's up moving around and doing some light stretching.  The plan is to finish out the calendar for the year, take it easy over the winter and come back strong for 2013.  Right now were watching the TIGERS game rootin for our boys!  We love you all and Thank-you for all your prayers. Much love....Mark & Lesia

Apparently this was a long time coming. Around eight years ago, Farner was diagnosed with a heart condition and told it was just a matter of time before he would need a pacemaker. "He's making a lot of effort to not let the stiffness set in so he doesn't lose range of motion."
