The Illusion - Did You See Her Eyes/Falling In Love (1969)

Jeff Barry, famed songwriter, had a small streak of hit singles in mid-1969 to early 1970, comprised of this, Andy Kim's "Baby I Love You," and Robin McNamara's "Lay A Little Lovin' On Me".  This is the only one of the three to sound like straightforward rock - and it is rather heavy, too.  The flip side leans more toward soft pop.
