Yesterday (Ode to a Black Hole)
One more quick post to say that I’ve put up another physics song which might be of interest - Yesterday as sung by a poor explorer venturing into a black hole.
In other very cool news, I’ve discovered that one of the education lecturers on campus has been regularly giving out copies of my Pi Song on Pi Day each year - I contacted her and she was “honoured” to meet the author! 
Hehehe…ain’t fame wonderful!
Have a good weekend, all!
And what about your copyrights?! Apparently the song was really popular (or at least was regarded as such) if it was given out by lecturer so often.
