I figured this out in about 5 minutes just before getting together as a small group. It
worked for us to sing it, but it may be off. Corrections welcome!
verse 1:
A#
I can hear the roar it's a mighty sound
F
Your love is an avalanche
Gm
I'm overcome
D# A#
I'm overcome
verse 2:
A#
With a clash I'm tumbling down
F
I'm wildly moved
Gm
I'm overcome
D# A#
I'm overcome
Chorus:
