I sang....
Some Miku song with another Miku, she knew the lyrics, I just vocalized...
I think I would up taking the stage when somebody needed a third for 'Ready Steady Go', and maybe one another song...
I was the REALLY LOUD girl who sang 'Raion', last opening theme to Blood+ plus, by band Jinn.
It was the short version, and the lyrics were the long versions, and it wasn't kareoke, so I was kind of sad. I waited a long time, just for tv version!?
I was happy with my singing though, so often in kareoke, people are so quite you can't hear them, not me, I was super loud.
