Here are my favourite triumphal tunes complete with MIDI references:

O Fortuna from Carmina Burana (Carl Orff)

Conquest of Paradise (Vangelis from 1492)

Triumphal March From Aida (Verdi) (Includes SATB Vocal Parts)
http://www.buffnet.net/~nfpress/Aida.mid

Chorus of the Hebrew Slaves (verdi) The action starts after the first 16 bars, the vocal parts should be much louder.

And from Bron's suggestion in case you haven't heard it (I hadn't) here's Danse Macabre by St Saens
