It's being noted around here since the twin cities of Fargo-Moorhead is where the plane was headed when it went down. People were already gathering in the arena when the news came so local promoters looked to local talent to fill the bill. They grabbed a Fargo teen, Bobby Vee, who was seen by the national promoters who were already here and the rest is more rock history.
As a historical side bar, Prior to that date, a very young Bob Dylan spent about a year here playing with Vee's band on his way from Hibbing, MN to the big time.
I used to work with woman who saw Holly, Valens and Bopper on their second to last show the night before. Memorable to her because that's where she met her husband. She said that when one band was playing, the other bands were mingling and goofing in the crowd so it was a real party atmosphere. Not like today where security prevents any contact with the performers.
