Doing a Triggerfinger. Orignates at radio station 3FM at a show called "Giel" by radiohost Giel Beelen in the Netherlands. In the show musicians play a cover of a song that is currently in the Dutch charts. At the 15th of January a band called Triggerfinger covered the song "I follow rivers" by Lykke Li. The cover made it to the first place in the dutch charts and stayed there for 6 weeks. Performing way better than the original song which only made it to the 2nd place.
