My DH and I had Zip-A-Dee-Doo-Dah as our recessional!!! It made everyone laugh, which was exactly what we wanted... just a happy event!
We used iTunes... search "zip-a-dee-doo-dah"... the artist we used was Johnny Mercer... it was exactly what we wanted, however, there are also BUNCHES of other arrangements (some are listed as zip a dee doo dah [w/o dashes]).
I hope this helps! We did all our music ourselves, so iTunes was our friend! We liked not having to buy the entire cd if we only wanted 1 song.
They have lots of other Disney stuff too... we also liked Steve Tyrell's album, Michael Crawford's album, and Dave Brubeck's album... all different Disney stuff you can get on iTunes.
We also really enjoyed Jim Brickman's "The Disney Songbook", but I just looked and it's not on iTunes anymore, but
Amazon sells it!
I hope this helps!!!
Best wishes!
