When
Chuck Berry plays at Finlandia-talo, Helsinki, Finland, Europe, his performance is well-below his usual standard because the octogenarian rocker is suffering from a bad cold. He takes the trouble to apologise to the crowd for his singing. The show's promoter will end up regretting having booked Berry when, two years later, he is made to refund 50% of the ticket sales by Finland's Consumer Disputes Board for putting on a concert at which an artist's performance was well below what the audience reasonably expected.
