“When you die, you go to Willie Nelson’s house” (Austin musician saying)

Austin prides itself as the “Live Music Capital of the World.” When a rock ‘n’ roll legend dies, he or she might go to “rock ‘n’ roll heaven.” In Austin, if you’re a good musician, it’s said that “when you die, you go to Willie Nelson’s house.”
 
Waylon Jennings possibly originated a form of the phrase (first cited in the 1980s), but it’s been popularized by Kinky Friedman.

Texas was flooded by storms that dumped twelve inches of rain on the Lone Star State Monday. It resulted in a lot of lawlessness. When residents of Austin were told to go to higher ground, the Democrats moved the party over to Willie Nelson’s house. (Argus Hamilton)
