19 Broadway is delighted to host a special concert featuring the original members of the Mad Hannan’s (Derek Smith, Dan Duffy and Jerry Hannan) after the screening of their movie at the Mill Valley Film Festival. This year’s Mill Valley Film Festival presents the music documentary, Mad Hannans. Popular local band Mad Hannans has had its share of creative differences and personal tragedy over the years. But this intimate tribute to the soulful, fraternal music group is not only a love letter to Marin County but a testament to the strength that can be found in self-expression.
