I watched once, a interview Rick telling he was very drunk and he does't know how song to play in a concert intro, then he told to each member of band (not all together) the opening song, and then the concert began and they started play, but the detail: he was drunk + he told a different song to each member, and everyone played a different song. In the end of concert they thought 'we're f*cked' and in the next day the newspaper: rick wakeman and band played a genial opening song.
