Celtic Moment

My niece will be graduating from high school next year and Im making a video slide show for the party. The program I am using will also allow me to set it to music the only problem is i dont know what music to play in the background. Right now there will be 4 sections: Her by herself, Her with her mom, Her with her dad, and Her and her friends. The music i have picked is Gary Allan “Tough little boys”, Maroon 5 “She will be loved”, Lee Ann Womack “I hope you Dance”, Dionne Warwick “Thats what friends are for”, and The Corrs ” So young”. What other songs would you recommend

Not Kids bop or anything like that just old silly fun songs.
I don’t want anything rappy, hip hoppish, r&b ish or anything like that.These kids get enough of that at home, I just want to expose them to different types of fun music from different regions of the world. Reggae, Conga, Brazilian, Celtic whatever.

I’m an avid fan of Celtic music, although I seldom ever (whether in this genre or others) follow an artist or group fanatically – usually I only like one or two songs by them. I’ve listened to some more ambient Celtic stuff but recently have taken an interest in more lively Celtic rock. So can anybody suggest me some particularly noteworthy songs/bands that work in this genre?

To be pickier still, I’m not particularly big on the heavy metal, nor the delicate harp/lullaby esque stuff. I like pieces that are lively, remeniscent of the folk of Scotland and Ireland. Although I classify it as “Celtic rock”, I am particularly fond of pianos and strings. Something with a nice strong rhythm, meditative, but very folklike without being too fairytale-esque. At the same time, nothing too heavy.

I’m rambling at this point. I know no two songs are alike, but I’m basically looking for some songs as described above. An example of a pseudo-Celtic rock song I’ve been quite fond of lately is, well, “Celtic Rock” by Donovan: http://www.youtube.com/watch?v=RQaSMgqgH1o

I’m not too big on the sound distortions, but this is basically the kind of hardiness I want in a Celtic song.
Nice suggestions thus far, although I’d still like to find a group that is a bit less dense with the instruments while still having a nice rhythm. Ideas?

I am taking my mom there next week, just for a day, and I thought it will be a good idea to try some nice Welsh food)))
So if anybody can recommend a best/very good restaurant of a sort with nice, traditional interior it will be great!

cheers ))
