Trouw “chameleon” + “Singers” [00:30]# Two commercials that illustrate the claim of Dutch newspaper Trouw, which is “We listen.” Which is also what the quite spectacularly filmed chameleon does before catching a fly. In the second commercial we see two singers side-by-side. The number they are performing is the old favorite, “Happy Days Are Here Again.” Since the guy singing the bass part has a much stronger voice, however, one can only guess at this. In the second take, he had been moved upstage, and now the song sounds the way it should.
