Music has always been a focal point in the Demmin household, with many vocalists and keyboard artists in the family. As a crooner in the classic tradition, singing the great standards of the 30’s, 40’s and 50’s is his greatest joy, with the Glenn Miller favorite,“Serenade in Blue,” his trademark piece.
