It’s over. It’s finally over, no fooling.

After 26 years of touring the country and hamming it up classically, P.D.Q. Bach (aka composer Peter Schickele) is finally taking himself off the truck with the collapsible cow.

The end comes, appropriately enough, on April Fool’s Day--Monday--at the Pasadena Civic Auditorium.

But Schickele, the maestro of mayhem, is not kidding. It really is his swan song in the “Farewell to Touring” concert, featuring highlights of his comical career as P.D.Q. Bach, the “last and least of the 20-odd children of J. S. Bach.”

The program is conducted by Jorge Mester, Schickele’s longtime friend from the Juilliard School of Music. It features excerpts from Schickele’s musical shenanigans over the years, such as the “1712 Overture” with exploding balloons and “Prelude to Einstein on the Fritz,” a musical poke at Philip Glass’ minimalist work, “Einstein on the Beach.”

The concert is at 8 p.m. at the auditorium, 300 E. Green St., Pasadena. Tickets are $18 to $35, and are available at the auditorium box office or all Ticketron outlets.
