Some wild English tune:
"Sha la la la la la la
La la la la la la la la"

from Phoenix – Bourgeois Lyrics on Rap Genius

Meaning

Perhaps referring to the song by the English R&B group Small Faces

Or the recent arctic monkeys song “the hellcat spangled shalalala” wich was a top 20 single in Bleigum and UK
