Several actors or crew from Sesamstraat have been interviewed, including the Muppets themselves. Voice actor Paul Haenen, who plays regular character pastor Dominee Gremdaat, has also mentioned his vocal resemblance to Bert (and briefly done his laugh). Other frequent guests have included Wim T. Schippers (Dutch voice of Ernie and others), actor Aart Staartjes, and writer Hans Dorrestijn. In 2009, Sesamstraat/Sesame Street harmonica player Toots Thielemans was interviewed about his Jazz Master Award. [1]
