Morissette Amon became a guest on A1's Take You Home, an online show mounted in place of the boy band's concert tour, which was cancelled due to COVID-19.
The Kapamilya singer and A1 member Ben Adams performed a duet of the 2000 hit "Like A Rose," while the other members played the instruments, and did back-up vocals.
The other three members of the British-Norweigian group are Paul Marazzi, Christian Ingebrigsten, and Mark Read.
The five-minute video collaboration was released on April 20, 2020.
Before the performance started, Morissette, who resides in Manila, and Ben, who is based in London, talked about staying indoors.
And when it was time for them to perform, Ben introduced Morissette to the fans as his "most favorite singer in the world."
Smiling, Morissette said, "He's just being nice! Thank you. It's an honor, thank you."
Here is the video of Morissette's online collaboration with A1:
Their virtual duet of "Like A Rose" was not their first collaboration.
Late last year, Morissette and Ben recorded "This is Christmas," and, on November 10, 2019, performed it live on ASAP Natin 'To.
