The main riff is transcribed here without Kossoff’s soulful bends (at the 15th then 18th fret of the second string) as otherwise there would be no definitive statement of it in the whole transcription! Watch the grace note hammer-ons, plus the quarter note bend in bar 2.
likely played by Paul Rodgers and snuffy Walden, these parts are tight and percussive, so walk the line between ‘tight but loose’.
Here, the rhythm guitars play noticeably different parts. We’ve gone with the arpeggiated chords and left the powerchords on the backing track. The lead guitar makes an entrance for bars 19-20. This sounds more authentic if you relax towards the end of the phrase.
