Yes, their voices were on the same pitch!
Whitney, as a live performer is like no other artist.
I encountered a traffic accident yesterday. The car which I was driving a motorbike, and ran on the side changed a slanted line of it suddenly and hit a motorbike. I fell down, but, fortunately, got off with a scratch. I thought that a motorbike was dangerous utterly. Even if this is careful, there are not winning chances if I hit a car. It has been spoiled on my Saturday.
I am sleepy, and I do not stand during work recently. I don't know why. Probably I think that spring is the cause. It is hard to stay in the office all day. We are not allowed to listen to music during work. Now I am looking forward to GW. I think I need to take a good rest. I have a problem on my ear since last year. According to the otolaryngologist, it seems to be a thing by stress and sleep. I hope to recover soon.
