Admittedly it was partially "the time, the place, the circumstance" that made this version of the song really strike home but I fell in love with it and will admit it was played several times that evening.
I like the regular version, but the acoustic rendition is my favourite version. The words seem so much more poignant and it really shows the power and quality of the lyrics.
The Foo Fighters - Everlong (Acoustic)
EDIT: I now really want to learn guitar so I can learn this song :)
