Help Identify song from commercial

Whats the name of the song from the commercial for some sort of online air ticket website where 2 parents are planning a vacation and then their son walks into the room. Then they think about what he might do when they’re gone and a song that goes “we’ve got to party,to party!” or something similar plays. Also I’ve heard this song in a recent beer commercial(bud light i think) This song is stuck in my head and I’d like to hear the full version.

Could it be Andrew W.K.? He is quite fond of partying.

Yup, it’s Andrew W.K.
