This piece has had a nice little life for weddings and is great offertory music. A little Celtic melody with a central piano section that suggests the classic hymn "Amazing Grace". This is a semi-live recording (flute is synth sample here). I might try this with an Irish pipe and post it here soon.

This prelude originally performed at a worship service in 1991. Though completely unintentional, their is an old Lutheran Advent hymn buried in the fabric of this piece.
