They get on their motorbikes every night, weekend and bank holiday of the year to help people in desperate need of blood and other essentials for life.
And now a group from the Norfolk Ukelele Society has done what they love to help Norfolk Serv, also known as the Norfolk Blood Bikes.
The keen musicians raised £700 through a concert at the Garden House pub in Earlham for the charity, which is entirely run by volunteers.
Club member Colin Rump raised £200 of the total through a rendition of Hev you got a loight boy?, originally by the 'Singing Postman' Allan Smethurst.
Peter Hunt, who is a member of the society and also volunteers for Serv, said the concert was one of a series of fundraising events being put on at pubs throughout the year in support of Blood Bikes.
Mr Hunt said: 'The Norwich Inns have named Serv as their charity of the year, so all 60 pubs who are members are holding events. sky dives, cake bakes, you name it. We're hoping to raise something like £50,000 in total for the year.'
Craig McLaren, secretary of Norwich Inns, said: 'We are very happy to work with Blood Bikes and hope to raise as much money as we can and give them publicity so more people are aware of the work they do.'
Mr Hunt said Blood Bikes was a worthy cause which saved lives.
He said: 'It's a pretty special charity, run by local volunteers transporting blood, plasma, platelets, samples, vaccines, factor VIII, donor breast milk and other urgently required medical items to hospitals.
'This service is provided free of charge by volunteers who receive no financial compensation and covers the whole of Norfolk.'
Mr Hunt said the charity often used motorbikes to transport to the products, but also had cars to use when more storage space was needed.
Serv costs about £3,000 per month to run, and receives no government funding. The service is only able to operate through donations from members of the public, fundraising events and corporate sponsorship.
Mr Hunt said he started volunteering for Blood Bikes after his wife became seriously ill and needed several transfusions. She is now fit and well and she too raises money for the charity.
