I played my Pa Go Go and vinyl East Coast pressing of Cameo 428...both versions of "Midnight Hour" are exact. No differences.
And of course, "96 Tears" is full length on Pa Go Go, but has the early fadeout, time is also shown as 2:38
The deadwax has a Bell Sound raised relief stamp, and the EY letters hand-etched. There is also another tiny imprint stamp, but it is difficult to decipher...3 M's, perhaps?
Bell Sound in NYC then mastered and created stampers of both songs for the pressing plant.
Credit on Pa Go Go is Rudy Martinez, both songs as pictured above. The Cameo vinyl pressing credits the Mysterians for both songs. Ed Arguello is also noted.
