English Translation

We are cowboys!
Gallavanting about the universe
Kicking about bad guys
We're chasing bounties!
Go Go BeBop!  Fly Fly BeBop!
Four people all together

Go Go BeBop!  Fly Fly BeBop!
We're fast as lightning!
Ah! cool spotted pattern   [1]
My happiness is reflected
In your wet eyes   [2]

We are cowboys!
Cavorting about the stars,
What bounty head we're chasing won't escape
Go Go BeBop!  Fly Fly BeBop!  Four people all together

• Repeat

Go Go BeBop!  Fly Fly BeBop!  Shoot Shoot BeBop!
Hmm,
Hmm,
Always starving! 

[1] "Ikasu" means "cool" and "buchimoyou" is a spotted design or pattern; here it is probably a poetic way of referring to the stars.

[2] The word "kanpai", in the line "My happiness reflected in your wet eyes", is usually issued like "cheers!" when making a toast. Here I felt it referred more to simple celebration (the line might also means, "The reflection in your eyes makes me happy/makes me celebrate").
