We now know why KISS canceled a concert in Poughkeepsie, NY and performed on Friday (4/16) at a Beverly Hills benefit without Paul Stanley.  He was tending to a torn tendon in his bicep that had to be surgically re-attached.  Stanley posted to his Facebook page over the weekend that he is sporting stitches and has a screw in the injured arm to keep the tendon anchored and adds that he should be good-to-go with time to spare before his band opens its Freedom To Rock tour inBoise, Idaho on July 7.
