you may consider the Rolling Stones to be relics but they are not by game standards, the simple answer is just to religious items. To whoever has the most domestic at the time... I did suspect you had to exceed them all but this was not the case when I ran a Kupe rock bands game. Get the highest domestic tourist number down is the name of the efficiency game, you will probably have to swap civs as you really do see their domestic tourist drop, so the main opposition will change. If you look at the result screen of the Kupe game I did not change but just thrashed the original leader to see if that is all you had to do.
