In 1971, Henry moved from New York back to Tampa, FL and began a small country/rock band called Sienna which as named after a college in Loudonville, N.Y. One interesting fact, band member Sean Emmitt, is the son of actress Kim Hunter (Dr. Zira in "Planet Of The Apes") from her second marriage.

Although the band lasted less than a year, the band members continued on and even worked together on later projects. Right after Sienna ended, Henry Paul and Monte Yoho joined a small group which Monte had been a part of a couple years earlier called the Outlaws. After that Outlaws began touring and were signed to Arista Records and have now gone on to become one of the greatest Southern Rock bands in history.

Seven years after the break up of Sienna, Henry once again joined forces with Jim Fish in the Henry Paul Band. On the HPB's debut album "Grey Ghost," they recorded one song which they had done back in the days of Sienna called "Wood Wind." It was in no way a hit song, but it was a nice tip-of-the-hat to their old band.
