"What Good Are You To Me" (and more) -- Markos Vamvakaris

This is exactly how a band should respond to a fight amongst the patrons.  When everyone in the outdoor taverna is cool, calm, and collected, the band sticks to mournful songs, but once the brawl starts the musicians respond with vim and vigor

Here's all that I know...

This is an excerpt from the 1962 film "The Accused of Love" which starred Giorgos Gavriilidis.  

Either the notes (in Greek) under the video are a bit convoluted or my friend Google Translate is recovering from a hangover, but I had a difficult time with the translation.  The first song, "What Good Are You to Me"* seems like pure Rebetica, the last song "My Beloved Angel"* seems a little more upbeat and 1960's ish.

Here's a helpful hint for musicians of all genres -- always keep an upbeat tune (like "My Beloved Angel") in your pocket in case a fight breaks out at your gig -- Here in the Pacific Northwest of the U.S., my friend Ian's band used to make sure that the Chicken Reel was handy when things got heated, but if I ever join a Greek band, I know what song to play...

* Given the translation that poor little Google struggled to produce, these titles could be completely wrong...
