That meant a number of days though, with me rushing to clean for a last minute showing, while the children waited, trying to stay entertained, without messing up their clean rooms. One of the days, while I was busy cleaning a bathroom, and the youngest three were (I thought) playing a video game, I started to hear a racket - sort of half singing, half chanting, followed by bursts of laughter, coming from the room they were in.
I figured they were playing some sort of computer game that called for them to repeat silly characters, or morphed their voices, or something like that. I was surprised the older girls, who were reading in the living room, hadn't complained about the noise (normally they would have) - except that it was strangely rhythmic. Then, G (age 16)'s voice joined in, adding a melody over the top of the chanting, and I realized they were singing a sort of impromptu a cappella song. It was rough, but it was pretty cool.
Naturally, as soon as they realized I was listening, they stopped, and refused to sing again.
The next day, hoping to encourage their creativity, I Googled "a cappella for kids" and came up with the video below.
The children still won't sing for me, but I have to say, we have a hands down, family favorite song for summer.
