Tony Maudsley, Adam Gillen and Shelley Longworth, who have all joined the Derren Litten comedy for the latest run, said that they had "great fun" with the '80s girlband, who cameo in the second half of the series.
"Bananarama were great fun! I loved them. They were fantastic," Gillen told DS. "They were brilliant girls - really glamorous and really, really funny. I didn't know what to expect, but they weren't prissy or self-conscious at all."
Longworth commented: "We did a scene together in Neptunes and we went out for a meal together. They were great together those girls."
Maudsley added: "One of the highlights for me was Bananarama. Working with the girls in episode five was just brilliantly exciting. I grew up with the girls in the '80s and know them well and I can promise you that they didn't disappoint."
Ex-Blind Date presenter Cilla Black makes a cameo appearance in tonight's Benidorm, which airs at 9pm on ITV1.
