Source of the nile

I'm crying all alone in the rain
Though it's not as bad as it seems
I'm crying tears of joy
Although my team's unemployed and dead
Lisa lost her arm

I finally found the source
Of the Nile river, of course
I've watched good men go mad
I've heard Livingstone's dead and gone
Not coming home

I've dined with cannibal tribes
And all sorts of new diatribes
Watched the animals eat
I've watched as they've considered me for a meal
Honey, I'm not comin' home
