Singer Sarah McTernan has acknowledged the "phenomenal support from home" that she has been getting from Irish fans in the lead-up to the Eurovision Song Contest.

Sarah will represent Ireland at the 2019 Eurovision in Tel Aviv with the song 22.

"It's been phenomenal, the support from home, people from my school, my hometown (Scariff) and from Ennis, everyone messaging and saying `keep doing what you're doing and we're all behind you" and stuff like that. So it's really nice to have that support. "

She has just done her second rehearsal in Tel Aviv and problems with a prop, which had occured in the first rehearsal, have been mostly ironed out.

"Today, I think we all, myself especially, eased into it, I was way more comfortable. I actually enjoyed the performance, I had fun. Obviously, there's always room for improvement."

She has had some problems with wisdom teeth, but a lengthy sleep from 6.00 pm to 6.00 am the previous night means she is well rested and enjoying the walks and strolls around Tel Aviv. Sarah visited a fine Italian restaurant and has been appreciating the local cuisine too.

"I'm praying to god my outfit fits me next week because the hummus is just absolutely incredible over here, " she says."

The singer enthuses about the Denmark and Australian entries and particularly Iceland's Hatari, who, she says, " are on the ball with their whole performance."
