I’m among those who found them lacking in substance, but I don’t discount anyone’s enjoyment of them (except maybe when I’m visiting my sister-in-law’s house at Christmas). Jackson Berkey is/was a fine pianist. In 1978 he released a wonderfully performed and recorded solo classical piano album on their American Gramaphone (their spelling) label called “Sunken Cathedral.” Gorgeous playing and sound, if you can find a copy.
