Sesamstraat Theme is the opening theme song of Sesamstraat. The song was originally sung by a chorus of kids. The song has been remade a number of times over the years not only for the show's opening and closing credits, but also for inserts. One of the earliest and most distinctive versions includes a harmonica solo performed by Toots Thielemans. But there was also a kind of reggae version, instrumental version and mid 80's it was sung by Frank and kids.
