EntertainmentInterestingWillie Nelson bought a Martin guitar sight unseen in 1969 and later named it Trigger. He has played it on stage ever since, and his pick has worn a hole clean through the top. An Austin luthier named Mark Erlewine has kept it playable since 1977, bracing the worn top so it can go back on the road. Willie is 93. On September 26 he closed Farm Aid on the same guitar.26 days ago
