This is a version of Swing Low Sweet Chariot that Sara Brown, conductor of the Bangor Commnuity Choir, learnt from Mollie Stone, a conductor at Chicago Children's Choir.
Dum dum ba dum dum dum dum dum ba da dum (ad inf & beyond)
Ah ah ah
Coming to carry me home (many times)
Swing low sweet chariot
Ah ah (several times)
I looked over Jordon and what did I see (several times)
A band of angels coming after me
Hear Bangor Community Choir singing this song in the music room of Penrhyn Castle.
