Dancers and diners enjoy Peter Karsti Band's music during Oktoberfest festivities. The band played German music Sept. 14 during WaterFire Sharon at Apollo Maennerchor Club. Doppler Adler Band plays from 8 to 11 Saturday during the second weekend of the traditional festival that celebrates the harvest with German beer, food, oompah music and the fellowship of gemutlichkeit. Prost!
