kurdt: that's a remix of the opening theme which is called "Monkey Magic", not "Gandhara." Gandhara is the ending theme and I've already posted a link to that in a previous post. Both were sung by Godaigo. I love the Karaoke clip for Gandhara as it shows the members of Godaigo actually travelling through India.

Here is the original opening theme.
Here is the English dub version. Same song but different opening narrative/edit.
