Anon and Kanon may have come from real twin singers. Twins don't always have the same voice, but they normally have similar voices, especially if their identical twins.

Notice how Yamaha tends to cater to professional producers and they have so far, as far as we've known, used singers which are professional levels or able to give professional quality singing results. Unfortunately I've explained several times before the problems with using professionals... Yeah, you get better singing results... But you can produce common traits since the music industry can be very formulaic at times, producing manufactured results based on popular trends. So as a singer gets more and more training or experience, oddities and things that set them apart from other singers may be lost.

And with the existence of modern producer tools, you don't even need the singer to improve, you can made the singer sound as samey as the next by auto tuning them or whatever.

So the problem with Anon and Kanon being "bog standard" is pretty much in their design. In fact... Of the vocals in the V3 era, I'd say half of them lacked stand out qualities and were typically. I remember when the only "bog standard" vocal was Meiko... :-/

God I haven't used "Bog standard" since I left Essex. Its always a fun phrase to use. :-D
