"let the good times roll in case God doesn't show"

.... the following is either an advertisement for engaging popular culture with your children OR
an advertisement against same

This morning i heard my 6 yr old singing this line
let the good times roll In case God doesn't show

turns out w/ a little help from google that the song is by Fall out boy and called Thnks Fr Th Mmrs
Anywho... it struck me that this line is akin to saying

Stuff your face if the caterers don't show
Dance around if the band doesn't show
Throw me a pass if the football can't be found
Turn on the TV since the electricity is out.

It felt oxymoronic. And this is the way I spoke with my son.... there is no deeper conviction i have (see Hebrews 11 and acct of Moses' life) than that it if God "doesn't show (up)" then it is impossible to have a good time.
But in further reflection, perhaps this line is more like what Paul said
If the dead are not raised, “Let us eat and drink, for tomorrow we die.” What do you think?
