I hate it when things are forbidden for “security reason.” I just heard on the radio that umbrellas will be banned at Rihanna’s upcoming US concerts. Apparently that’s because during her European tour lots of people came with umbrellas to the concert, opened them when a certain song was played, and the risk of injury was believed to be too high.
The song in question, by the way, is actually good, not just danceable, as shown by this awesome acoustic cover.
(Youtube is replete with acoustic versions of dance songs; this version of Crank Dat manages to be sillier than the original, a feat that would seem impossible.)
