This past fall I went to the Kimmel Center in Philadelphia to hear the music of ABBA come alive with a Finnish group named Rajaton. (See second photo below.)
Remember ABBA?

Rajaton has 6 members
I saw them at Carnegie Hall with the New York Pops. Very entertaining.
Yes, they are entertaining! ellensue
