Typo

I played for a funeral this week. There was a typo in verse 3 of the hymn below (vv.4-5 not shown). "Yeah" should be "Yea". Why do people not check? Also, I was due to play Handel's "Largo" at the start and I asked for a cue from one of the funeral directors as the start of the service was to be different to normal. Although he said he would let me know, he didn't, so the vicar launched into the service after I had stopped improvising (after proper pre-service voluntaries). Anyway, the congregation stayed to hear the closing piece and I played the "Largo" after that as they departed.
