I completely understand! I lead worship at my church as well, and some years ago, I can remember singing the words to one song, but to a melody of another with the same chord progression!🙀 Ironically, the people went along with me until I had a fit of giggles and called for a 'do over'! Another time, I was looking at the screen in the back for the worship team with the lyrics and sang line 2 and 4 and then 1 and 3, even though they were on the screen correctly! How I managed that one, I'll never know!
I like to say when these things happen......'it's worship LIVE- not Memorex'. God understands, and you were praising Him! That's what really counts! Take care and thanks for sharing!
Thanks
