Hearted children's songs

This is the second and, unfortunately, the last album, which was added the 4 siblings. It's a shame that the siblings have not continued their music career, but where already the LP "Heissa Juchhei" was such a terrific success. With this last album "The red flashes Blank" the 4 have again shown what they can do. Besides hearted children's songs on this album are also thoughtful title, such as "Let me not down," when it comes to separation.
In particular, I would like to highlight the title "A little imagination", since all 4 voices really get into this very meditative song to advantage, because each of the 4 children has sung a verse.
Keeping in mind that the children were very young when they recorded the CD, it is remarkable with how much enthusiasm they have sung the songs, because they had pleasure in it we hear out of each individual title.
A real shame that it has remained only at 2 productions and I wonder what happened to them and why they have not gone on with the music.
