I went to this place in Lafayette for used lps, 45s, and they also had some 78s.
Pioneer Trading Post
5903 Johnston Street
Lafayette, LA
It's on Hwy 167 going south, just south of Acadiana Mall on the same side of the street in a little strip mall with Albert LeBlanc Mobile homes next door.
I saw many Goldband 45s in good condition, some on Lanor, Jin, Swallow,etc. Ask for Walt Broussard.
