I just looked it up. Jennings gave up his seat to the Big Bopper. Another member of Holly’s band, Tommy Allsup, gave up his seat for Valens.
“Jennings gave us his seat to the Big Bopper.”
The story goes that they flipped a coin and Waylon lost. Waylon turned to Holly and said, “Well, I hope your old plane crashes.” Holly responded, “I hope your bus breaks down.”
That interchange probably stuck with Waylon for the rest of his life.
Dion gave an interview where he said he was supposed to have one of the seats. Perhaps I conflated it with something else…😔
