Reminds me of one of the first recordings I made, I cut a track at the end of the day with a flubbed note on a Kubicki bass which was a big, obvious 8th note. packed up my kit since it was the end of the day thinking I wouldn't get a chance to record the track again. I could have done it the next day, but no one seemed to have heard that awful bum note! It made it into the track and it was only when I pointed it out post mastering that anyone else noticed! I'm not sure how since it sounded like a bloody trumpet exploding.
On the same track, the drummer managed to go out of time, and since the drum track was being recorded with a MIDI hookup and a click track, a good take was punched in over the top since that part of the song was "sparse" with only drums, keys and bass playing. I didn't have the chance to re-record my part and it was left as is, which makes it sound as though my bloody bass goes well out of time since I played along to the original, "slow" drum track!
We live and we learn, eh?
