Albacore looks like pale tuna, while Escolar looks strikingly white. Mostly, it is because suppliers and restaurants mislabel fish, either out of ignorance or fraud.
Another reason for the confusion is that Gempylidae, the family of fish that both Escolar and Oilfish belong to, has several other names.
Michael Brown was a classically trained keyboard player ( the only real musician in the Left Banke). When it says, "You won't see me follow you back home," does that mean he will follow her, but she just won't see it? In fact, it is a Cor anglais or English horn, which is in the oboe family, but is deeper and richer in sound.
He gets together with some older NYC guys and at 16 writes this gem because he has a schoolboy's crush on the beautiful blonde girlfriend (Renee) of the bass player. He was clearly influenced by the Burt Bacharach song "Walk on By" which had been a huge hit for Dionne Warwick in 1964 (see those lyrics about walking down the street and crying). Unfortunately, the session player who played this heart wrenching solo was not documented on the session record!
Escolar is the most controversial fish that you are likely to find in your fish market.
