"It’s Showtime" brings a whole new level of energy with the intense vocal showdown in "Tawag ng Tanghalan All-Star Grand Resbak." In the singing competition's current season, 48 alums called 'resbakers' are back to compete against each other. They are divided into four groups, in which one group will be completely eliminated every two weeks.

Even the hosts of "Showtime Online U" (SOU)—the “It’s Showtime” gap show that airs on Kapamilya Online Live (KOL)— feel the tension and adrenaline from their set. "Minsan nanonood kami habang kumakain kasi lunch time 'yun tapos napapatigil kami kasi sobrang gagaling ng contenders do'n," said Lorraine Galvez, who is one of the best “Tawag Ng Tanghalan” alums herself. 

Wize Estabillo, adding his signature humor, quipped, "Nagtataka ako kung bakit hindi nila ako sinali do'n."

Wize burst into laughter when asked if he had any advice for the TNT contestants. "Magbibigay ako ng advice? Wow! I'm so thick! Ang kapal!" he joked, making the entire Kapamilya Chat studio laugh. On a more serious note, while he may not be a singer, but as a former contestant in the noontime show’s “BidaMan” segment, he encourages the 'resbakers' to simply enjoy the experience. "Yes, nasa competition ka, pero at the end of the day, iba 'yung happiness at fulfillment na mabibigay no'n sa sarili mo. At basta nag-e-enjoy ka sa ginagawa mo, parang success na rin 'yun, eh," he imparted. 

Lorraine, on the other hand, knows exactly what it feels like to be in their shoes, having started her own career in TNT. That’s why her biggest advice is to make the most of this opportunity. But truth be told, she knows these singers don’t need much guidance—they’re 'resbakers,' after all, the best of the best. They already understand passion and skill. All that’s left is to give it everything they’ve got. "Give them a good show," she enthused.

Apart from "Showtime Online U," Wize and Lorraine are also hosting "PGT Exclusives," the online show of "Pilipinas Got Talent Season 7.” PGT airs Saturdays and Sundays on Kapamilya Channel, Kapamilya Online Live (KOL), A2Z and TV5, starting March 29 and 30.
