On 8th October, 2003 surfer Al Marzian sent me the following information:
Mark Janza may actually be Albert F. Marzian. Some Rag Time writers feel that Janza and Marzian are the same. Both "Janza" and "Marzian" are from New Albany, Indiana. The writers told me there are many similarities in their music.
Many thanks Al! Does anybody out there in cyberspace know more? If yes, then please let us know.
