Fall Out Boy announced today that they hope to become the band heard 'round the world: Pete Wentz and Co. are going for a Guinness World Record as the first group to play a concert in all seven continents within a nine-month period. The rockers kicked off their trek in Johannesburg, South Africa, last summer and have since toured through Europe, Asia, Australia, and North America. They're scheduled to play in South America (Santiago, Chile) on March 23, followed by a show on King George Island in Antarctica on March 25 (as part of a global warming awareness campaign with Greenpeace), where they will be officially crowned holders of the world record. They would take their place in the Guinness Book beside Chicago rapper Rebel XD (fastest rap at 852 syllables in 42 seconds) and British singer-songwriter Katie Melua (deepest concert at 994 feet below sea level, on Statoil's Troll A gas rig, off the coast of Bergen, Norway).
