So its a v2 vocal and the likes of Gumi, VY1, miki, yuki, etc. Not many could sound like Miku back then like they do now. Miku's vocal was especially distinct then and stood out more. I think VY1 was close to a adult-ish Append for Miku and sounded more like her in higher pitches... But Gumi had a rep for not being able to be flexiable on her tone range... Miki was a vocalist clone at times, able to sound like other vocaloids with the right tuning, but still distinct in her default.... It would be the pitch for her. Most other vocaloids have too much power or softness in either direction of Miku... Makes them harder to sound like her. VY1 and miki are likely the best two at it.

I would list the songs you know UTAUVC0401 and see if any rings a bell for the OP.

Better then nothing and you might get lucky. It could even be a cover version they heard. :-?
