The brothers will just be coming out of their final exams, but the pair will be performing to a sold-out Vicar Street.
Seán is doing his Leaving Cert, while Conor is sitting his Junior Cert, and they have seen their gig sold out in 15 minutes this morning.
Don't be too disheartened though, because the Wicklow siblings have added another date at the same venue.
They started off busking on Grafton Street when Conor was 11 and Sean 13, but last year they made it to the quater finals of the X-Factor Live shows with Simon Cowell as their mentor.
The future is looking bright for the lads!
