After a couple days of editing video and burning it to discs, Marv’s music is playing more or less non-stop in my head, especially when I run or ride. It’s perfect exercise music. “Nobody Knows You (When You’re Down and Out” is a little bluesy, good for fat-burning or recovery, and “Going to Chicago (Sorry But I Can’t Take You)” and “Some of These Days” make a good soundtrack for an interval session.
A casual Googling unearths about a jillion different flavors of these tunes performed by a wide range of artists over the years. Marv seems to have taken his “Some of These Days” lyrics from an Ella Fitzgerald version. Count Basie could be the source for “Going to Chicago,” but Marv’s version has a whole lot more lyrical meat on its bones, some of which may have come from “Chicago Monkey Man Blues” by Ida Cox.
But that’s folklore for you — every story changes in the telling.
