What if the old logo still has fans?
You keep the feature those fans name and you change what can no longer be read or is no longer true. You do not revert to the whole old logo because of one comment, and you do not ignore the people who recognise you by it. Ask them to point at what they miss: the colour, the letter or the drawing. If they cannot say, the attachment is to the venue, not to the file. A vote is held and the old logo wins by half, mixed with the new one. The result is neither, and the banner looks odd.
The new mark with that feature built in, and a line for anyone who asks on the floor. The sheet makes clear the old file does not come back in stories.
