From the intro of a song (<https://www.youtube.com/watch?v=KS2t7l89Lm0>)

The English words are being sung in English.

I understand everything in the bolded sentence except the use of 〜て行く(or maybe
it's some other construction I haven't recognised?)

Exactly why is the て there? The sentence would make sense if it was just
さあ行くわ.




[さて](https://dictionary.goo.ne.jp/jn/88595/meaning/m0u/) (> さあて) and
[さあ](https://dictionary.goo.ne.jp/jn/84286/meaning/m0u/) are separate
interjections. Both can have several possible English renderings that might be
rather confusing, but さて is uttered when you shift the focus of interest to
another topic, and さあ is a word to spur someone to take a (dynamic) action.

In your context both can be filled in, but they tell different things. If I
had to make some (shoddy) translation:

> さあて行くわ _And now, I gotta go!_  
>  さあ行くわ _Here goes!_
