They don't sound much sweeter than Trigger.The first time I saw Willie at Toronto's Skydome, he a started with Whiskey River as he usually does. He was having problems with Trigger and changed to another guitar half way through the song. The sound was awful in the dome.
The next two times I saw Willie was at the Capitol Music Hallin Wheeling, W.V. a beuatiful theatre with incredible sound. Trigger and he were quite a team those nights.
Open Mike, Willie always plays until they make him go home, I think that a lot of it is that they want to give the audience their moneys worth, but I get a sense that he absolutely loves performing.
