They gave blood, sweat and quite a few tears, as they played the drums non-stop for three days – comfortably passing the world record by several hours.
But, for the team of drummers from Dereham, there may be a few more tears yet, after they were told their efforts could not be accepted as a new world record.
Although the musicians, from JDT Music Academy, may not have missed a beat during their 72-hour challenge last August, the same could not be said for the video camera recording their efforts.
A technical hitch meant the device failed to record a few hours on the first day of the attempt and invigilators from Guinness World Records have told the group the record cannot be verified.
The same team had held the record twice before, and the last challenge was an attempt to reclaim the title. Despite their intense disappointment, the team has agreed to launch a fresh tilt at the record.
Nia Howe, co-owner of JDT and one of those involved, said: 'We're gutted. It has taken us some time to come to terms with it but we are over that now and we are definitely going to do it again.
'We have given it a huge amount of thought because it is not easy, not just for the drummers.
So many people gave up a huge amount of time over that weekend to help us.
'We just want to prove we did it last time and prove we can do it again.'
The camera did not record four or five hours on the first day of the challenge, and the back-up system also failed.
The team discovered the technical difficulties during the attempt but had hoped the record would be accepted as they had a number of witnesses who signed statements of the bid's authenticity.
However, the arbiters have now given a final verdict that no record was set.
Miss Howe said the team had learned from previous attempts and would be even better prepared this time. She added the academy had received great support from everyone she had spoken to.
She said: 'I started making inquiries to our previous sponsors and volunteers and the responses have been 100pc positive which is overwhelming really.'
