I've read that the American style of singing is really just neutral English language singing. But a co-worker was convinced that almost all singers singing English language songs sing with a typical American accent, even if they have a non-American speaking accent (be it Scottish, English, Irish, Swedish, etc). I kick myself for not thinking of The Kinks at the time. I brought up The Beatles, but the co-worker didn't think so, though it's plain as day to my ears. Brought up the lead singer for The Cranberries, but that was dismiss as singing with a Irish lilt. So... who sings and retains most of their non-American accent while singing English language songs?
