As Brown County Civic Music Association tips its hat to members who have remained loyal for at least half a century, the vocal quintet, Amarcord, will make a return appearance Nov. 15 for the association.

The group last sang on the series in May 2002.

The singers are former members of St. Thomas' Boys Choir in Leipzig and sing a cappella works.

"They're the German version of the King's Singers of the United Kingdom," said Roger Bintz, who helps book the series for the all-volunteer organization that has brought classical concerts to Green Bay since 1926.

The organization will recognize its 50-year members during the concert and at a reception afterward that is a gift of the Sylvia Kaufman memorial. Kaufman served on the Civic Music board of directors for 51 years. She died in 2008.

Members to be recognized are Marcella Berendsen, Cal and June Brockman, Madeline Centen, Henry and Elsie Mae Hall and John and Lois Kirschling.

The Halls joined in 1953 for a $6 season membership "and still have their check registers to prove it," said Rita Kilmer, executive secretary.

Centen has been a member since the 1944-45 season.

"Marcella Berendsen recalls the popularity of women's hats with feathers in the 1950s," Kilmer said. "Following board discussion, programs were stamped with a request to remove hats during the performance."

The first half of Nov. 15's concert, titled "European Romanticism," will consist of such selections as "Serenade d'hiver" by Camille Saint-Saens, selections from "Sechs Lieder fur vierstimmigen Mannerchor by Felix Mendelssohn, "Ctverice muzskych sboru" by Leos Janacek and "The Green Anthology" by Edward Elgar.

The second half, "Nine-Hundred Miles From Home," will consist of folk songs to be announced.

In the group are Wolfram Lattke and Martin Lattke, tenors; Frank Ozimek, baritone; and Daniel Knauft and Holger Krause, basses.

In 2002, Amarcord won the German Music Competition for Chamber Music.
