Birds of Prey Musical Number on Batman: The Brave and the Bold

Gail Simone tweeted this clip on Saturday and I haven’t been able to get its catchy tune outta my head since.  Hitting “Replay” doesn’t much help.  But I wondered who a splashy Bird of Prey musical number was aimed at?  Especially with the double entendres:

Batman throws his batarang,
What a weapon,
What a bang!

There’s also a cute nod to the famous Charlie’s Angels silhouette 15 seconds in. I’ve never watched Batman: The Brave and the Bold mainly because the animation hasn't appealed to me.  However, I loved what I saw here in terms of character designs and movement—I believe those are Silver Age versions of Catwoman and Black Canary vamping it up with the Huntress.

I’ll set my DVR before passing any further judgments on this series.
