a lot of operetta (Danilo, Armand Brissard in Der Graf von Luxemburg, Pâris, Barinkay, Guido in Eine Nacht in
Venedig, Graf René in Fall's Madame Pompadour, both Orlofsky and Alfred, Orphé, Zarewitsch, Mister X,
Raoul in La vie parisienne, and above all Sou-Chong), but also some opera (Max, Fra Diavolo). Guest appearances (most
often as Danilo) in Hamburg, Munich, Malmö and at the Deutsche Oper am Rhein.
From the mid-1960s, Grundén switched to buffo parts at several Stockholm operetta theaters, and appeared as a drama
and film actor in Sweden.
