Hey guys, figured out how to play Can't Hold Us on a standard tuned ukulele. 
Included tabs with chord names, as well as a relative timing. Enjoy!

   Em      D       Bm       C        
E––2–2–22––0–0–00––2–2––22––3–3––33–––––––––––––––––––––––––|
A––3–3–33––2–2–22––2–2––22––0–0––00–––––––––––––––––––––––––|
C––4–4–44––2–2–22––2–2––22––0–0––00–––––––––––––––––––––––––|
G––4–4–44––2–2–22––4–4––44––0–0––00–––––––––––––––––––––––––|

And also, for the intro, you only play the C twice, not four times.
