Led Zeppelin - Since I've Been Loving You (Live at Madison Square Garden 1973)

"Since I've Been Loving You" was one of the first songs prepared for the Led Zeppelin III album.The song was recorded live in the studio with very little overdubbing. It was reportedly the hardest to record.

John Paul Jones played Hammond organ on the song, using the bass pedals instead of a bass guitar. John Bonham's preferred drum pedal, the Ludwig Speed King model 201, squeaks during the recording, and has been called the "Squeak King".

The opening and closing lyrics of "Since I've Been Loving You" are nearly identical to the 1968 Moby Grape song "Never". The song is a slow blues in the key of C minor.
