I dunno if its a "Recovery Song" per se, but it makes me think of the Rooms and the Fellowship that I found there...

Ben E. King - Stand by Me

When the night has come
And the land is dark
And the moon is the only light we'll see
No I won't be afraid, no I won't be afraid
Just as long as you stand, stand by me
And darlin', darlin', stand by me, oh now now stand by me
Stand by me, stand by me
If the sky that we look upon
Should tumble and fall
And the mountains should crumble to the sea
I won't cry, I won't cry, no I won't shed a tear
Just as long as you stand, stand by me
And darlin', darlin', stand by me, oh stand by me
Stand by me, stand by me, stand by me-e, yeah
Whenever you're in trouble won't you stand by me, oh now now stand by me
Oh stand by me, stand by me, stand by me
Darlin', darlin', stand by me-e, stand by me
Oh stand by me, stand by me, stand by me
