Both Sides Now
I came across these two very different versions of Joni Mitchell's classic song 'Both Sides Now' which first appeared in 1969 on the album Clouds.
I don't know when the second version was recorded, but this was obviously done much later in Joni Mitchell's career and the difference between the two is very striking.
The original is youthful and optimistic, yet still manages to to cast a grown up eye over life and loves; the later version is more solemn and reflective, but still beautiful and bitter sweet.
