..... The front cover of The Life of Lewis Charlton, A Poor Old Slave (which probably dates from around the time of the Civil War)

Charlton recalls slaves being marched out of the city, singing 'Don't talk about suffering here below/ But talk about love like Jesus',
and a slave named Larry Porter who 'was a devout Christian and insisted on attending Methodist meetings on Sunday where he led the singing.'
