Hello,
I am a big fan of OLD SKOOL and I am also a musicphile....for an untraditional wedding march check out Quincy Jones' Back on the Block CD, there is an absolutely beautiful song entitled Septembro, Brazilian Wedding Song. Trust, it will bring you to tears.
Check out Donny Hathaway's version of A Song for You, Stevie Wonder's Songs in the Key of Life would make a wonderful backdrop....Let's see what about EWF? Earth, Wind and Fire, stop playin'!
Anita Baker's Compositions, Ramsey Lewis' Ivory Pyramid CD...If you email me, I will look at my collection and give you some more suggestions. Good Luck!
