The Royal Marines have broken the existing Guinness World Record for the longest group drum roll - an attempt launched by Hollywood stars Tom Hardy and Harrison Ford.
The Royal Marines' Corps of Drums began their effort on Wednesday evening and finished as world record holders this morning.
The existing record stood at 28 hours, 19 minutes and three seconds, with the new record extended to 64 hours.
The event was part of a year of celebrations for the Royal Marines who mark their 350th anniversary this year.
Taking inspiration from their founding on the October 28 1664, the Corps of Drums referred to the event as 1 record, 6 teams, 64 hours.
40 Royal Marines' buglers took part in the record-breaking attempt, from Royal Marines School of Music and all five bands - Portsmouth, Collingwood, Plymouth, Commando Training Centre Royal Marines and Scotland.
Each drummer played for 15 minutes at a time during the record attempt drumming for a minimum of one and a half hours.
The record attempt was based at the Tower of London throughout and the drummers put on regular demonstrations, and offered members of the public a chance to have a go for themselves.
Corporal Bugler Stuart Warmington, who came up with the idea, said: "To have finally broken the record is amazing. It has been so long in the planning and rehearsals. I am overwhelmed with how well it went.
"Not only am I really proud of everyone who took part, but I am thrilled that we were able to support the Royal Marines Charitable Trust Fund who do such incredible work on a daily basis."
Lieutenant Colonel Nick Grace, the Royal Marines Band Service principal director of music, said: "It is a great honour to accept this record on behalf of the Corps of Drums. I am extremely proud of all of them."
Richard Kenworthy, head of fundraising at the Royal Marines Charitable Trust Fund, said: "I would like to say a huge thank you to the Corps of Drums and all the public for their generous donations. The money raised will help us make a huge difference to those in need."
