On this 1933 recording

Clarence Ashley clearly sings
There are a house in New Orleans
They call the Rising Sun
Where many poor boys to destruction has gone
And me, oh God, for one
"There are a house in New Orleans" and "many poor boys to destruction has gone".
So what "are" and "has" are doing there? What's going on with plurals in this text?
Mother wiki says: "Ashley was born ... in Bristol, Tennessee in 1895, the only child of George McCurry and Rose-Belle Ashley". That doesn't suggest English is not his native tongue.
Is it a dialect?
