For those of us who are at least familiar with this dramatic story-song, and those who even like it (I do), which other singers could also have delivered a respectable performance of it ?
The 1968 hit by Richard Harris is perhaps the best known, followed by Donna Summer's disco stab in 1978. I believe Andy Williams also recorded the song.
P.J. Proby perhaps would have gone way over the top.
Sammy Davis Junior - a likely contender.
Glenn Close - would be worth hearing.
Tom Jones - see P.J. Proby.
Shirley Bassey, assuming she hasn't already recorded it at her peak.
Can't think of any others just now.
