Sixties doo-wop singer Frankie Valli has had to cancel a concert in Bangkok - because of Thailand's political unrest.

Promoter BEC-Tero Entertainment says Wednesday's performance was scrapped because of difficulties associated with the unrest and for the safety of the audience.

The promoter said concerts by other visiting artists, including Avril Lavigne in February and Eric Clapton and Bruno Mars, both in March, are still on schedule.
