The Pasadena Roof Orchestra

The Pasadena Roof Orchestra (commonly abbreviated to PRO) is a contemporary band from England that specialises in most genres of music of the 1920s and 1930s, although their full repertoire is considerably wider. The orchestra has existed since 1969, although the line-up has frequently changed. It has achieved success outside of the United Kingdom, most notably in Germany. The PRO was formed in November 1969 by John Arthy, a baker who moonlighted as a BBC session bass player.
