This is only my second tab, but I'm wicked confident that these are right!
These chords sound more like the recorded song when you half strum half pluck the verse.
On my ukulele,I strum down with my thumb on the top 3 strings and then use my index
finger on the bottom string to strum up.( If this doesn't make any sense, I'm very 
sorry) And the strumming pattern is Down down up up down up.
