The band "Highly Strung" raised £700 for Kings College Hospital Charity when they performed a special benefit gig at Oxhey Hall Community Association off Broadlands Lane, Oxhey Hall, last week.
The band performed in memory of their good friend Stuart Lyddon who was given a bone marrow transplant at the hospital.
Stuart passed away nine years ago, but since then his friends have been fundraising to provide creature comforts, such as bedside fridges, for patients in the Derek Mitchell Unit and Davidson Ward at Kings in London where Stuart was treated.
Through their activities, such as an annual charity golf day, they have now raised in excess of £7,000.
The band’s drummer, Shaun Laws from Oxhey, said: "What a brilliant evening. We not only raised such great amount for the charity, but had a lovely time getting together with over 120 friends, family and neighbours from Oxhey Hall."
A spokesman for the charity said: "Every donation to Kings College Hospital makes a difference. Thanks to our generous donors, we bought the fastest CT scanner in Europe, which you may have seen on Channel 4’s 24 Hours in A&E. It completes a full body scan in 15 seconds, compared to the usual 10 to 30 minutes.
"All donations help provide the very best care to patients and enable researchers to develop further life-changing treatments."
