The music and chords are also in "Songs of the Great American West" (Dover 1995) by Irwin Silber. The chord set is a bit embellised from the ones Joe found so i will include them

Dm G Dm G Dm G Dm
Come (G)all you sons of (Dm)Liberty
un(G)to my rhyme give (Dm)ear
"Tis (F)of a bloody (F6)massacre
You (C7)presently shall (F)hear,
In [Bflat(Dm)]splendor o'er the (G)mountins
some (Am)thirty wagons (D)came,
They were (G)'waited by a (Dm)wicked band,
oh (G)Utah, (C7)where's they (Dm)shame?

Musical instruction added: "Not slow: accent every chord. cut time, half note = 70
