There are a few things to consider:
* Privacy: As a public figure, Gareth Evans' personal life is his own. Information about his current activities and whereabouts is likely not widely available.
* "Only Boys Aloud" is a choir, not a permanent group: The choir is made up of boys and young men, who all move on in life. Gareth may have continued singing, gone into another career, or chosen a more private life.
* Social Media: A good place to start looking for information is by searching for Gareth Evans on social media platforms like Facebook, Twitter, or Instagram. If he has a public profile, you might find updates about his life.
