Argentinian guitarist Ivan Singh (before you ask – his great grandfather was from India), who came to Chicago only a couple years ago, was a very loud opening act. I should have brought my ear plugs. Once I found a place to hang out suitably far away from the stage, I was able to enjoy his music.

But I wasn’t there for him, so I was happy to hear him fire up Sweet Home Chicago, which, predictably, meant he was closing his act.

After a break, blues legend Charlie Musselwhite entered the stage, harmonica in hand. I don’t think I was the only one there for him.

A fair number of people in the park rose to their feet to start dancing as soon as he raised his instrument. And I’m talking young people, though the older generation, folks who knew of him from way back when, some of whom didn’t see to have changed their wardrobe since, were plentiful throughout the crowded lawn.

Musselwhite, who did not disappoint, came to Chicago in 1962, and has played with all the local greats. He told a Sonny Boy Williamson story that must have been funny – the people in the first few rows laughed – but I couldn’t hear the details, even though I had by then moved closer, relieved by the fact that he and his excellent backup band maintained an acceptable decibel level.
