JEDWARD'S boundless energy is putting other Eurovision competitors in the shade. The Lucan twins have a gruelling day ahead of them with a further two dress rehearsals throughout the day, which don't finish up until 3am.
And this is before they face into the competition against the other European finalists including Britain's Engelbert Humperdinck, 'Russian grannies' Buranovskiye Babushki and Italy's Nina Zilli.
However, John and Edward Grimes are staying focused on eating right and getting plenty of sleep.
"They are stocking up a lot on sushi. That's what they are being fuelled by," an insider said.
"They have a really healthy diet and know what is important to get them through the day."
The temperature in the capital of Azerbaijan has hit 33 degrees today but insiders said it is a dry heat and the twins are careful to keep rehydrated.
However, visitors at the contest said that the city is pristinely clean with very few insects or flies.
Irish commentator Marty Whelan decided to sample the sights and sounds of the city before he took up his commentating post for the semi-final.
He hit the local market and managed to haggle his way to getting a bargain €15 traditional Azerbaijani hat.
Meanwhile, Jedward had a day off yesterday in the sweltering heat of Baku as they waited for the conclusion of the second semi-final.
But when the entire show wraps, the Irish contingent will have little time to celebrate at the after party. The final Eurovision show ends at 4am and Jedward must be at the airport at 7am.
"It has really been a whirlwind for Jedward," a Eurovision insider said.
"They are constantly on the go and stun everyone with their limitless energy. When everyone else is fading and ready for bed, Jedward are there doing somersaults.
