misskipling's Red wedding

So I'm trying to set a mood with the music I'm using as at the wedding social we had in April (it's a party thrown in the couples honor to raise money for the wedding), the DJ just played middle of the road, 90's music. While it's not bad....I want something a little more memorable.

Think Frank Sinatra, Diana Krall and Micheal Buble (or however it's spelt!)

I'd like to have a piano/martini bar type of feel so does anyone have a play lists or artist suggestions for music ??
