Radio City Music Hall continues selling tickets to Lady Gaga in concert with old-time crooner Tony Bennett. Their album of jazz standards, Cheek to Cheek was released in September of 2014, and quickly rose to #1 on the Billboard charts. This is Gaga’s third consecutive #1 album, and at 88, Bennett maintains his distinction of being the oldest singer with a #1 hit. But aside from their NY Italian-American roots, what are these two doing together? If you consider Saturn, it’s obvious.

Gaga has the Moon at 11 Scorpio 27. She underwent hip surgery as Saturn stationed exactly on her Moon in February of 2013, perhaps forcing her to consider simpler, more basic music for a time. Bennett has Saturn at 19 Scorpio 29 and becomes for her the personification of Saturn – quite literally in the form of an old man (he experienced his third Saturn return this year). His Saturn conjoins her Moon, making long-term collaboration between them a very real possibility. And Gaga’s Saturn also trines Bennett’s Leo Sun within about a degree. If Saturn provides the glue that makes relationships stick, this commitment goes both ways.

And fascinatingly, they both make each other sound better! Lady Gaga is known as more of a Uranian type of performer – it’s often more about theatrics and technology than her vocals. While she actually has a beautiful, strong voice, you almost need to see her at the piano or raised on some contraption over the floor – there’s something missing from her solos. And Tony Bennett used to be able to sing, but that was decades ago. (A PBS broadcast of the duo’s concert showed audiences giving him a standing ovation for a solo – they’re just glad he’s still alive.) However something wonderful happens when they’re together and they seem to compensate for any liabilities in each other’s performances. Such an emphasis on Saturn in their relationship suggests that they’ve worked on it.

As Saturn passes into Sagittarius in 2015-2016, Gaga will experience her first Saturn return. With so much success behind her, it’s hard to remember that she’s still only 28. It’ll be interesting to see what her next act will be.
