The beloved musical “MAMMA MIA!,” which features ABBA’s timeless songs, celebrated its four-year anniversary at Mandalay Bay on March 15. It’s the longest-running Broadway show on the Strip. After yet another rousing performance that had the audience dancing in the aisles, a certificate of senatorial recognition was presented to cast members and a party was held at Border Grill. There was fabulous food, like the green corn tamales, and the cast mingled with guests well into the night. Photos by Isaac Brekken
