At the end of the most recent 8-4 play podcast, they finished with the famous Rainbow Road song. What's that you say?
As a kid I used to do this constantly. Given my age most of them are SNES / Mega Drive songs, but here's a few that I did -
Forgive me for my Catholic-ness but this one stands out
My sister and I used to sing "hey ho, the lord is good, the lord is full of good-ness / hey ho, the lord is good, the lord is full of good-ness.
Jesus
Jesus
Wonderful Jesus "
And so on. Yep.
Another two, the next one is again Mario world
Once the melody kicks in (and yes I am aware Mario world does variants on the same theme)
"Close all the windows.
You'll let the heat out
You'll let the HEAT OUUUT
You'll let the HEAT OUT".
and so on.
I'm not singing today because I ended up staying up until 5 am finishing 2016 Doom last night... I'd not stayed up to game so late in 15 or more years.
