I just saw an episode of Mr Bean and once again heard the choir sing in Latin. Based on what I remember hearing and what I found online, the four segments sung are:
- Start: Ecce homo qui est faba — Behold the man who is a bean
- End of first half: Finis partis primae — End of first part
- Start of second half: Pars secunda — Part two
- End: Vale homo qui est faba — Farewell, man who is a bean
In all sources I saw the last line has est. I would expect es, since vale is addressed to Mr Bean (second person singular). I recall seeing second person verbs in relative clauses, for example: Tibi, qui amicus es, donum do.
Is the est in the fourth line grammatical? Is it possible to use third person verbs in a relative clause to refer to second person this way? Is it indeed supposed to be est instead of es? I found no authoritative sources for the lyrics, and I cannot hear the difference clearly enough to judge by ear.
