Ho eyo he hum

Ho eyo he hum is a simple tune commonly sung in the city of Britain.

In Ultima I, the song is first introduced by Iolo, the bard, who sang it wherever he was encountered.

In Ultima II, several jesters and entertainers found throughout the Earth sang, "Ho! Ho! Ho!" - a similar, albeit much simpler, ditty.

By Ultima III the composition of the classic tune had seemingly evolved. Iolo still sang "Ho eyo he hum!" as was his wont, but now Gwino (likely a bastardization of Gwenno) added an accompanying "Muh eh oye oh!" to the song, reversing its phonetics.

In Ultima IV, several small children in Britain also happily sang "ho eyo he hum," possibly due to the tutelage of Gwenno and Iolo, the song's seeming originators, who were entertaining them at the time.

Ultima V: Lazarus
In the remake of Ultima V, Ultima V: Lazarus, Iolo's response to some commands is to sing this song.
