Sometimes, the process of writing pulls me down a deep rabbit hole. Such was the case with Gritty City Sirens and their upcoming pair of reprise performances of Adventures in OZ. I searched for the burlesque troupe on YouTube and found one of their self-promotional videos. The music for that video, which sounded at first like a Doris-Day-style charmer, was written and first performed by Ruth Wallis in 1968. The opening verse goes, "You gotta have boobs / if you wanta impress / tycoons and rubes / You need boobs to fill out a sweata / You need two, but three might be betta!" Ms. Wallis then explains, "That's one in the back, for dancing." And the song gets even racier from there.

Granted, 1968 wasn't the dark ages, but Wallis had been writing and performing such numbers since the 1940s. Her most famous number, "The Dinghy Song," made light of a certain seaborne "Davey's" limitations: "He's got the cutest little dinghy in the navy ... It's built for speedy action and it gets him into port." After radio host "Dr. Demento" introduced high school and college kids to her oeuvre, she was celebrated in a 2003 stage production, BOOBS! The Musical. (I'm not kidding about any of this. I never kid about boobs.) Wallis died of Alzheimer complications a few days before Christmas, 2007, at the age of 87. I suppose that's not a great way to psych you up for Adventures in OZ; but trust me, a few listens to such lost Wallis classics as "Drill 'Em All" and "Hawaiian Lei Song" (there's Davey again) will put you back in the requisite saucy mood. As Elphaba said, "Surrender Dorothy!"

Adventures in OZ, a curvaceous retelling of L. Frank Baum's The Wonderful Wizard of Oz, stars Polly Pucker Up as Dorothy, Heather Hostility as the Wicked Witch, Rosie Cheex as Glinda, Kitty Kisses as the Scarecrow, Olivia Phaze as Toto (the dog, not the '80s radio stars), and Ms. Hattie Hotpants as the Wizard. Both 2015 performances are benefits for Carol Milgard Breast Center. Last year, the Sirens were able to raise and donate $8,000. This year, the show has been retooled and revamped, pun intended - which is to say the cast has been shuffled a bit. Also, the press release notes, certain numbers were "tweaked to add even more c spice to the show." That extra consonant is a typo, but it did raise my eyebrows.

Did you know Baum's Glinda is the Good Witch of the South, not the North as in the movie, and doesn't take an active role in Dorothy's life until The Marvelous Land of Oz? The Good Witch of the North, who sends Dorothy toward the Emerald City and doesn't appear again until a cameo in book seven, is named Locasta or Tattypoo. Tattypoo! There, you see? Another rabbit hole.
