more HOG in MR!!

ABL has told me that moses was singing 'speechless' to astrid in episode 6.

Also

in episode 9...at the end. the family are together(well most of them) and they sing their 'song' the same one as the one in HOG!!! but they do different things...

unless that is a VERY popular song in HK i dont think that every family will be singing it?!?!
will they??
