Some of the shows I listed earlier as good promo spots are prerecorded and so are probably not suitable options, so here's an updated list of good promo spots Gaga should take advantage of for the new single. (This is assuming it comes out before the tour starts.)
March 17 - Dancing with the Stars Season Premiere
April 13 - MTV Movie Awards
April ? - Ellen
April ? - GMA
May 1 - iHeartRadio Awards
May ? - American Idol Season Finale
May ? - Jimmy Kimmel
Gaga, if you're reading this, you should go to some, if not all, of these to promote!
The poor soul, only capable of doing one performance every three months. Little worried about the artRAVE tbh unless she's just been holding back the entire time.
How is that gonna kill her? That's only 7 performances stretched over three months, with the most per month being three. I don't think that's too much at all.
Too bad its fake 
Don't do her like that, she's come a long way.
