Only In America 10 - Coconut Record

The transcript describes a unique event where Spamalot, a Tony-winning Broadway musical, celebrated its first anniversary by organizing the world's largest coconut orchestra. Around 1199 people gathered to play coconuts in a special rendition of 'Always Look On The Bright Side of Life'. The event was monitored by Guinness World Records, and participants received free coconuts. Spamalot, adapted from Monty Python and the Holy Grail, opened in 2005 to critical acclaim and now holds a world record.
