Ted Fredenhagen in 1990 organized the Class Act I Big Band in Naperville, Illinois. They named the band Class Act because they thought they would mostly play for class reunions. After Ted moved to Amboy, he reorganized and added some new talent and renamed the band Class Act II.

     Although Class Act II’s roots are in the big band sounds from the 40's a la Glenn Miler and Benny Goodman, the band has a sound and repertoire that puts it in today’s mainstream in the style of Michael Buble, Big Bad Voodoo Daddy and big-band renditions of current songs by Manhattan Transfer and Earth Wind and Fire.

     In June 2011, the band was hired as a surprise for a 50th wedding anniversary party. As the couple renewed their vows, a severe storm moved in bringing high winds and rain. The power went out and the band set up using only flashlights and candles. The storm subsided but there was still no power.  The band continued to get ready without the power to the microphones and lights. But just as the curtain opened, the power came on and the honorees were amazingly surprised as planned.
