Being the music lover that I am, I also submit for your consideration:

When Johnny Comes Marching Home - Jimmy Smith (For the family members and ancestors who were/are veterans)

Blue Note - CDP 591140

Symphony No. 9 in E Minor, Op. 95 "From The New World", Movement #2 (Largo) - Antonin Dvorak ( Although written with the story of Hiawatha in mind, African Americans have written words for this music and titled it "Going Home" ) Lazer Light Digital CD # 15 517

To Be Young, Gifted And Black - Donny Hathaway (For the younger folks at your reunion) Atlantic Records #A2 82092

And finally:

Lift Ev'ry Voice And Sing - written by James Weldon Johnson & John Rosamond Johnson - performed in this clip by The Choral Arts Society. (You can 'capture' the song to your computer free of charge with CD burn software).
