A producer in Perth, Australia...is putting together a musical based on the music of Da Bruddas. According to Michael Herrmann, who wrote the libretto, Gabba Gabba Hey is "a touching love story with colorful Lower East Side characters" set to the music of Johnny, Joey, Dee Dee and Tommy (the last of whom has signed on as musical director)
The Australian producer is most likely not advanced. But it is advanced for a Ramone to be involved. It would have been much more advanced if it were Joey or Dee Dee acting as musical director, which is impossible now (sadly). Of course it just may be that Tommy was the most advanced of them all. Hard to say.
Oh, and I don't think I need to remind you all of the outfits the Ramones wore.
