Mark E. Smith
This frontman mostly 'spoke' his lyrics, uncommercial.
Kim Carnes
Now this woman did 'Bette Davis Eyes' and she sounded like she just
woke up and like she was a whiskey drinker. .
Helen Shapiro
She was a teeneger and had a deep voice. She sung Walking Back to
Happiness also It might rain til September and tiptoe through tulips.
Dean Martin
This crooner sounded a bit tipsy. How do you
like your eggs in the mornin', Volare...
Wayne Newton
Now all I know about him is Danke Schoen, he had an androgynous voice.
Astrud Gilberto 
Girl from Ipanema... Astrud has no vibrato in her voice.
Marianne Faithfull
I know she sung 'As Tears Go By' in the 60s but also 'Broken English'
1979 which sounds electro
Shane MacGowan
This is one of the great messed-up frontmen but he is a bad influence 
because of the drink and cigarettes, as a teenager I thought he was 
glamorous - but fronting a band must be nerve wracking.
