"She's staying the hospital until Sunday. She's totally exhausted and drained, but absolutely delighted."

Crystal Swing,
made up of mum Mary Murray-Burke and her children Dervla and Derek Burke, shot to fame in February 2010 when a video of their song
He Drinks Tequila became a viral hit. The family went on to perform on the
Ellen show and
The Late Late Show, before hitting the road for an extensive tour of Ireland.
Speaking to the media when she first revealed her pregnancy, Dervla says Mary was overjoyed at the prospect of becoming a granny:
“I’ll never forget the day I told my mum." she said. "We were getting ready to play for a wedding. She was having a bad day and feeling really down. However, she burst into tears of joy after I told her." she said.
“She really loves the idea of being a grandmother.
Dervla continued to perform with the family throughout her pregnancy but now plans to take a well earned break with the newest band member.
