I'd like to think they're both well known in the CBBC audience. Layfield was a presenter for CBBC HQ until recently and has hosted The Dengineers and The Playlist. HRVY-no-vowels was on Friday Download in the early 10s and is popular with that demographic I'd like to think.

He last presented Friday Download in 2015, so unless you were at the bottom end of CBBC's demographic then, and still watching CBBC for that matter, I don't know
