CONSTANTA, Romania (AP) — Torrential rain has dashed hopes in Romania of setting a Guinness Book world record for Greece's famous sirtaki dance.

Romanians were attempting to break the world record for the dance made famous in the 1964 movie "Zorba the Greek" before a storm struck this Black Sea port on Saturday.

Organizers declared the attempt a washout, then had a change of heart and called people back to the beach in the port, 250 kilometers (156 miles) east of Bucharest.

The current world sirtaki record was set in Volos, Greece, in 2012 when 5,614 people danced.

Organizers in Romania claim more than 6,000 people took part in Saturday's record-breaking attempt. Guinness representative Seyda Sibasi Gemici declared the attempt invalid, however, saying it had become too dark to do an accurate count.
