Northwood and Pinner Liberal Synagogue in Northwood held a concert with American folk duo Julie Patchouli and Bruce Hecksel.
The event was attended by 115 people and raised more than £700 for Michael Sobell Hospice in Northwood.
Event organisers Phil and Diana Stone met the performers in a field at a folk festival in Sarasota, Florida, in 2014 and invited them to visit them when in London.
They became friends and, fast forward to May 2018, the duo played to a packed audience at a charity performance at their synagogue.
The American duo were on a tour of the UK and Europe and agreed to fit the concert into their schedule.
