Runrig guitarist Malcolm Jones required heart surgery last year
Celtic rockers Runrig have been forced to suspend a planned tour of Germany at the last minute due to a medical issue for guitarist Malcolm Jones.
He was fitted with an implant last year to deal with a heart problem.
However, a reported malfunction in the device has meant it now needs to be replaced.
The band said that the guitarist was in good health and their other concerts will go ahead - including an appearance at the Hebridean Celtic Festival.
Runrig were confirmed last month as a headline act at the festival's 15th anniversary event.
The band has not played at the Western Isles' biggest music event since 2005. It takes place on Lewis in July.
