Not sure what you mean by a "full" version, but Doerflinger's (from Maitland) is quite long -- 13 stanzas plus a variant final stanza.

Colcord's is shorter -- 5 stanzas -- but I'd still call it a substantial version. I'm too lazy to check every version I have indexed, but there are clearly a number of substantial versions; they aren't all fragments.
