Stereophonics stormed out of a gig on Friday (30Apr10) after frontman Kelly Jones was hit in the face with a sandal.
The Dakota rockers were performing at Fort Canning Park in Singapore when a concertgoer hurled the flip-flop at Jones, who halted their performance to pick up the object.
He muttered 'thank you' to the crowd before tossing the shoe aside and walking off. His bandmates are said to have followed.
Security guards then hauled the man responsible outside, before Jones and his bandmates returned to the stage to finish their set.
