From 1992, almost two years before I discovered his music.
The “impersonator” is the singer of a tribute band I’ve known about from about 1993/4-onward (pretty much since the start of my fandom) called T-Rextasy.
“T-Rextasy” was the media headline equivalent to “Beatlemania” in 1972/73. He was really very huge at the time. 5’4″ and so much larger than life.
