Music is in your family spirit! Bravo on your Dad and Mom! Your Mom, a radio star!
I am wary of “mega churches.”
My mother passed away last year, but she can still be heard on Old Fashioned Revival Hour broadcasts over the Internet--bootleg versions available on some sites as well as those from the official site. She never soloed on the broadcast, but I think her voice was better than that of the two designated soloists.
She left in 1957 so she could give her kids a religious upbringing in a real church--the Methodist Church--but she and my father would sing in many choirs over the next several decades.
