use Direbrew's Remote - Item - World of Warcraft, go to the drum kit and talk to the male goblin, tell him you came here to see the band and he will make a band play. When they start playing, /cheer at any of the band members are you will recieve the buff for 5 minutes.
This could be useful if you have the raid buffed up and need an extra 10%, as the remote takes your party there and it takes 30 seconds to get the buff. Just get summoned back.
Buff vvvvvvvvvvv
Pumped Up! - Spell - World of Warcraft
cheers.
