"Sing a song"

A PACES candidate must be a good singer. Afterall, it is a show about the skill to be a physician who is thorough and complete in examining patients. So, we need to sing after each examination.
1. Respiratory: I would like to complete my examination by checking the temp chart for any fever, sputum cup and perform a bedside PEFR.
2. Cardiovascular: I would like to complete my examination by checking the blood pressure, temp chart, fundoscopy for Roth spots, abdomen for splenomegaly and urinalysis for RBC & proteinuria.

This applied to other systems as well. So, what is your favourite song?
