SWEET OK SUPERSISTER

There must be some sort of an inside joke that I don't get. I have two albums by this group and although there are some mischievous tricks in the songs I never really liked them alot. As I heard that this group has made a comeback and a live DVD that is better than ever I though to give it a shot. I don't get it. Is this some sort of sircus prog? Should it be funny? It don't make me laugh... and certainly the music is not very special. Good playing yes, after 25 years of not performing. Well rehearsed. Not very interesting melodies but it flows OK. But why do they do those silly jokes? This could work in a kindergarden well. I'll recommend this to serious fans and collectors only.
