"I Dig Everything About You" by The Mob didn't chart on WLS, but it made it to a respectable #20 on WCFL in December of 1970.
A couple of other local gems ("extra extras", if you will!) that charted on WCFL (but not on WLS) include:
HAPPY DAY: Easy to be Free (#24, May, 1970); Heighty-Hi (#24, July, 1970) both sides originally issued on the Varpo label, eventually released on Uni Records; Everybody I Love You (#30, November, 1970) also on the Uni label. Could not find YouTube clips of these, but clips are available on their Facebook page (Happy Day Band). The band also did a lot of advertising music at that time, most notably for the CTA.
BOBBY TREND: Good Day (#19, November, 1970), released on Ivanhoe Records

"People and Me" - charted a few weeks on WLS in May of 1970, peaking at #32 (#116 on Billboard, did NOT chart on WCFL)
"Roll On" - the first of three singles on the tiny Sunlight label, reached #10 on WCFL in September, 1971 and #56 on Billboard, did NOT chart at all on WLS
"Long Time to be Alone" - peaked at #15 on WCFL, #93 on Billboard, did NOT chart on WLS.
"Someone, Sometime" - peaked at #19 on WCFL in April, 1972, #109 on Billboard, did NOT chart on WLS
One more local gem from 1965 that charted on WLS, peaking at #11 in May is "Say it Softly" by BOBBY WHITESIDE. He had a hand in The Family's hit "Face the Autumn" and later co-wrote Barbra Streisand's hit "Comin' In and Out of Your Life". This was released on the local Destination Records label.
