Katy Perry is leaving Las Vegas with a costume party

Pro tip: Try the beer-can bra.

The famous pop-top top should be a contender for the top prize as Katy Perry hosts a costume contest on Halloween. The event is less than a week before Perry’s “Play” closes its run at Resorts World Theatre on Nov. 4.

Guests to Perry’s performance next Tuesday are invited to participate in a “Best Katy” costume competition. One of three winners will be hand-selected (or, fin-selected by a Left Shark) for the chance to meet Perry after the show.

Costume contestants are to show up at 4 p.m., have their photos taken up until 6 p.m., and winners will be notified prior to the 8 p.m. show. All guests will be gifted a red mushroom temporary tattoo designed by L.A. artist Liz Kim.

Perry flew Kim in on Oct. 15 to ink a red-mushroom tattoo on her left hand. Perry gets a tattoo depicting every tour as those tours close out.

The “Waking Up In Vegas” singer realized only after the work was finished that her new mushroom is — permanently — on her ring finger. At least, it’s in full bloom (hah).

A ‘Wonderful’ effort

Las Vegas’ Social Issues Theater is staging “The Wonderful World of Was,” a musical “dramedy,” at 6:30 p.m. Thursday at Windmill Library Theatre. The production is also scheduled for Flamingo Clark County Library at 7 p.m. Nov. 10.

The shows are free and open to the public.

The production features original music written and arranged by L.A. Walker, with Music Director Elder Demieceo Benson and Marcia Norris and a seven-member ensemble making up the cast. The production brings to light the challenges of Dementia, for those who suffer from the condition and their caregivers.

The terrific Las Vegas Mass Choir, with director and founder James R. Smith and business manager Victoria L. Norman, is the featured guest. Go to thesit.org for intel.

Jam sesh, with costumes

The Funk Jam, founded by A.J. Johnson, hosts a performance and costume party at 10 p.m. Wednesday at OG Sand Dollar Lounge on the corner of Spring Mountain and Polaris.

James continues his fight against multiple myeloma, a blood cancer that attacks bone marrow. The great bassist is not 100-percent cancer-free, but says he is feeling much better, a lot more energy than months ago. He can still be counted on to rock the house.

As for the contest, the winner is awarded a $100 bar tab at Sand Dollar (and also, try the pizza). If you have a strong Katy Perry costume, wear it.

Cool Hang Alert

“The Bourbon Street Experience” featuring the seriously talented drummer YL Douglas (of Barry Manilow’s band) and some top New Orleans musicians, plays 7-10 p.m. Thursday at Maxan Jazz. The N.O. players in town for the new Bourbon Parade venue at Horseshoe Las Vegas. So we have an off-Strip, Vegas supper-club hang with sushi and a spice of Bourbon Street. We do it all around here.
