I did this in an afternoon and since there seems to be nowhere with full lyrics or chords I have been making educated guesses except when obvious. Chords used (in order of appearance): G Am C D Em F#m-(Not diatonic) Bm <Verse - Guitar isnt actually playing yet but these are the chords if you want to palm mute or something.> G You’re moving through me like a ghost G You’re the treasure I want most G You’re the feathers on the dove on the pole Am C Flies around, around, around my soul <Pre-Chorus - Strum each chord once and let them ring out> D C If I believed that I could help carry pain away from you D C I'd put my shoulder underneath anyway you want me to <CHORUS> G D When you need to buckle and bend Am C You can call on me to help you forget D C G D Hey, I’m on your side and you’re better than that you know G Am C Em I’ve been waiting here for you so long G Am C Em So I could give my love to you, I’ve had to break someone <Pre-Chorus - Strum each chord once and let them ring out> D C If I believed that I could help carry pain away from you D C I'd put my shoulder underneath anyway you want me to <CHORUS> G D When you need to buckle and bend Am C You can call on me to help you forget D C G D Hey, I’m on your side and you’re better than that you know <BRIDGE> F#m G C G Darlin’ you’re a long way from home F#m G C G I’ll do my best to help you feel you belong Bm D Now the rose pink kiss left on your cheek, C G Marks the mournfulness of distant things <Not sure of this lyric> Bm D It’s a pain, the biggest part of belief. <Not sure of this lyric either> C Now I rush to your relief, G C - and I won’t Let you down G C I won’t fail you now G C (intensify chord) I won’t Let you down……... <CHORUS> G D When you need to buckle and bend Am C You can call on me to help you forget D C G D Hey, I’m on your side and you’re better than that you know D C G D Hey, You’re in your prime and you’re better than that you know D C G D Hey, I’m on your side D C G D Hey, I’m on your side Hope this helps people learn this incredible song
