"Is it fixable?"
The short, painful answer to that one is, no. Sorry, the only thing that will remove crazy glue is nail polish remover and that will FUBAR the tag and the ink on it completely. At this point you need to do no further harm. Leave it as it is. Some dime-store white Elmer's glue would have done the trick and preserved the tag. I know - you wanted to get it done, but sometimes immediate gratification can be your worst enemy. Sorry it went south on you. No biggie, it's just a tag after all. If it's a good looking and sounding drum that's all that matters.
