I always am the old codger that digs up all the old crap like a dog that has so many bones buried in the backyard.
This does not contain a video, but this song by Led Zeppelin represented Robert Plant's first major written composition. Looking at today ( rare for a "fossil" like me...), you can see where his new ideas blossomed out of by hearing this one.
Some of the best Zep, including this, is very acoustic and understated. Plant says that they had to blow everyone's doors off to get noticed before anybody would listen to something as brilliant, yet unassuming, as this.
I loved this when I was 16.
Still love it.
