If you were a British teenager in the 70’s there were a select number of bands who seemed to appeal to everyone. Rockers with enough Pop for the teenies but also enough stomp for the ‘serious’ music fans. That ‘something for everyone’ appeal at the time has proved to be timeless, as evidenced by the appearance on Thursday of two giants of the era – Status Quo and Alice Cooper on a double bill at Bonn’s Kunst!Rasen.
