In which my phone joins in the fun

Student D is working on Volga Boatman. Working on the left hand, he free-associates and turns it into a thumpy minor boogie woogie bass. I start improvising the melody over it. Finishing, we both start laughing, and simultaneously shout "Volga Batman!"

Then I type myself a note to look up more information about the song, and guess what spellcheck does?
