The affected nerve in piriformis syndrome is the sciatic nerve. Collectively the tibial and common fibular nerve makes up the general term sciatic nerve. Since the sciatic nerve is so close to the piriformis it is acknowledged that the muscle plays a role in irritating the nerve.
They named the band Lynard Skynyrd after. Leonard Skinner, a disliked gym teacher / coach some of the members had in high school. Skinner later moved on to selling Real Estate in Jacksonville Florida.
Now, it must be re-negotiated again, with the estates of Allen Collins, Ronnie Van Zandt, and with Gary Rossington, to see if they'll allow the band to continue to use the name Lynyrd Skynyrd with Gary Rossington as the only living original member. IMO, Gary won't want to continue with the band.
