Translation of a song

Hi. so sorry. I dunno which forum to post to, I thought i can post here cuz its translation thread.

I hope someone can help translate a song for me, or at least explain what the song is about.

The song is from an old TVB series called Demi-Gods and Semi-Devils starring Kent Tong, Idy Chan and Felix Wong.

Sory for some strange reasons I cant cut and paste the chinese words here. It just ends up as ???.
Sorry my mandarin is not good. Can only pronounce the words, dunno the meaning :p

They have the translation for two of the themesongs but the other songs, the translations are left unfinished.
