Never liked the Matthew's Southern Comfort version of Joni Mitchell's Woodstock for the same reason. However CSNY's version was pretty good, because they did a complete remake - a bit like Nazareth's cover of her This Flight Tonight. Less sure about Vanilla Fudge's take on the Supremes You Keep Me Hanging On. At least it's not insipid.
Vanilla Fudge are a product of there time & LSD. They are at the forefront of 'Progressive' rock but still on the shirt tails of 60s pop. If you want some thing criminal try All The Young Dudes -- World Party No passion no feeling
Just heard for the first time ,and hopefully the last, Cilla Black singing Bridge over troubled water🤢🤢🤢🤢🤮🤮🤮🤮
Talking of Simon and Garfunkel covers, one that definitely doesn't belong in this topic is The Disturbed's Sound of Silence. I wouldn't necessarily say it's better than the original but a fantastic version in its own right. Another one I really like is The Bangles' Hazy Shade of Winter.
