for sure they willllllllll and many places including coffeeshops will open till wee hours...
for example the 2002 World Cup did rock Singapore. the final game (brazil vs germany) suntec the large tv screen showing it and so many pple gathering there to watch. even the cars on the road wun move, stay there and watch, till pple honking at them hehee...
then when brazil wins, many soccer fanatics run round the road with the brazil flag and even ran in front of a bus and shout "goalllllllllll". the bus of course stop
so u will expect the mood to be here in tiny spore
