Neither of those sound like it. I was trying to find it last night but was unsuccessful.
I remember the chorus was really fucking lame
"Trudeaumania, people screaming, shouting, crying.
Trudeaumania, dazzling voters without trying (he was young and hard to handle)"
And another line was "he had style, you could tell, wore a rose on his lapel."
Like kindergarten style rhymes lmao
