Dia dhaoibh go léir,

I was watching a music video by the Connemara singer Seán Beag Ó Flatharta on YouTube and the lady introducing the song thanked the audience using an expression which sounded something like "Go luaith Dia dhaoibh".

Can anyone tell me the correct expression?

Go raibh míle maith agaibh

Bhfuil nasc agat?

Cinne, seo é an nasc:

Idir 17 and 30 soicint isteach sa bhfísean

It's at 37 seconds, I believe.

Also, if that's it, she's not thanking them, but wishing them safety/health/etc. (I can't pick up the exact verb).

Go gcasafaidh muid ar a chéile aríst, go X Dia dhaoibh

I feel like an idiot. The video has subtitles. In Irish.

Here's what it says

Go gcasafaidh muid ar a chéile aríst, go ngnóthaí Dia dhaoibh

Go raibh míle maith agat galaxyrocker! Tá sé sin ró-iontach ar fad!
Is mise an t-amadán! You have just made me aware of the subtitles feature of YouTube

Don't be too worried about the subtitles. Generally, I've found, they don't exist for Irish. I actually clicked on them to see what English approximation would've been given for a clue, and was shocked when it was actually in Irish.
