Take a look at this Irish dancing video which shows the world record being set for the longest line of dancers performing Riverdance.
The performance took place in Dublin in 2013, when over 2,000 Irish dancers descended on the banks of the River Liffey.
They came from 163 different Irish dance schools in 44 countries all across the world.
The dancers came from as far afield as Mexico, Japan and Uzbekistan. While there were over 2,000 at the event, the official number that took part in the line was 1,693.
The 1,693 dancers surrounded both sides of the River Liffey as the 1km line crossed the Samuel Becket Bridge.
The video follows the line of dancers up and down the Liffey and over the bridge.
They danced uninterrupted for five minutes as thousands of delighted locals cheered them on.
The event was organised by Abhann Productions and they brought in one of the original Riverdancers to lead the record attempt.
New Yorker Jean Butler was the lead female dancer on that famous night in 1994 when Riverdance was introduced to the world during the interval at Eurovision.
The record attempt was part of a 2013 tourism drive called The Gathering which sought to encourage people around the world with Irish heritage to come to visit the country.
Ms Butler said: “I am delighted to have had the opportunity to celebrate The Gathering through Irish dance with thousands of people over the course of this weekend.
“Riverdance has played a big role in my life but it has also played a big part in bringing the joy of Irish dance and music to many people throughout the world.”
The dancers smashed the previous record for the longest Riverdance line, which was set by an impressive 652 dancers in Nashville, Tennessee, USA.
