I was under the impression that 'Band Concert' had its titles restored back around the time of the first Treasures set (if not earlier for one of Mickey's anniversaries) with no need for recreations.
I don't have the disc to hand to check, but I'm pretty sure that BAND CONCERT still has the reissue titles on the Treasures release (red burlap background and standard white text).
Frames from the actual original title (surviving in LoC and shared by David Gerstein) use the grey UA titles. The actual title card is pretty plain – a gray background with the text "THE BAND CONCERT" all in one line in red. You can see it here:

The "Joseph M. Schenk Presents" text (which Bobby mentioned) is missing and the title card itself uses a grey background with large green text for "THE BAND CONCERT" with each word on its own line. You can see them in this video:
The video above is from 2015 so it's possible the original titles have been reinstated since then (I don't have Disney +), if so it'd be good news to me!
To add to the confusion, there's another relatively recent version of this cartoon with different titles again. The 'Have a Laugh' version has a title card which uses art from the short. It's a close up of Mickey's music stand, with "THE BAND CONCERT" replacing "Selections from Zampa" (it's the same green typography as the other version, but carefully distored to match the perspective).
