One fan, who was asked by the event's host to sing "Like A Rose" before the boys arrived, was asked to get up and sing again.
"What are you going to sing for us today?" asked Ben as the reporter approached the mic. "It's like X Factor!"
When the reporter said he was nervous, Ben – who originally wrote the song for his mom – said, "Shall I come and stand next to you and sing it with you?"
Watch them duet the chorus of "Like A Rose" below!

Later, when a reporter shared that no one danced with her during her prom when A1's "One Last Song" came on, Christian got down to dance with her as Ben and Mark sang in the background.
Of course, there were cameras flashing and squeals all around. Watch!

The two performances were just a sneak peek of the boys' concert at the Kia Theater on October 23, and in Cebu on October 25 at the IEC Pavilion.
Aside from their songs from their recent albums, A1 also said they would perform songs at their Philippine concerts that they haven't performed in years – Mark even added that they're set to do a few dance routines, too!
