Fame and riches don't guarantee a happy life, I guess. So many artists reach that pinnacle of success only to fall to pieces. Patsy Cline with I Fall To Pieces off of her '63 The Patsy Cline Story album.
I was looking for an acoustic guitar cover version and found this excellent live one by Joe Bonamassa off of his 2013 An Acoustic Evening At The Vienna Opera House CD.
Cream's version was good, too. Another great version was by Jethro Tull's original guitarist Mick Abrahams' band Blodwyn Pig off of the 2004 All Said And Done compilation CD.
And a rockin' live, 11 minute version of Cat's Squirrel which midstream takes quite a departure. Geezus, what a performance! I envy anyone who might've been there.
