The Buckinghams, Time & Charges, 1967 on Columbia.
In case the cover photo didn’t make the Beatles comparison, the rear jacket notes say: “[The Buckingham”s] talent will do for Chicago what the Beatles did for Liverpool”
Love their take on “I’ll Be Back” and “Mercy, Mercy, Mercy” which is a Joe Zawinul tune originally recorded by Cannonball Adderley.
“Foreign Policy” nicely pulls JFK quotes into Chicago style brass band rock with flutes.
