Hi

I am looking for the title of a US movie I believe from the 60's. A youth came to town, entered a basement bar and started playing I think a guitar. Later he went to live with a family (might have been his own) and seduced a girl of the family who had a baby. I always thought this was Lee Remick but I can't tie that up with anything.

At the end he sets fire to a house and I believe dies in the fire or possibly it was his brother who died.

I can't think of anything else, hope you can help.
