Has anyone heard of this song?

[addyb]

Years ago at school my sister used to sing a song that went something like this - "I love the mountains, I love the sky" - it was sung as a round with the second part being "bum far rah rah, bum far rah rah".

We aren't sure if the music teacher made this song up, as we haven't heard of this song since.  Thanks in advance to anyone who can shed some light on this - it might stop my sister singing it !!!!
