[2] The album's best known songs included "Rally Around the New Flag", which lampooned the extensive political battles over the then-new "Maple Leaf" national flag design, and "The Pill", which satirized the then-topical issue of the birth control pill.

The Evaporators reference The Brothers-in-Law in their song "Gerda Musinger" (about the woman of the same name) on the album Ripple Rock.
Nardwuar the Human Serviette sings, "The Brothers-in-Law sang about her first / but let's further whet your thirst!"
In 2008, the Quebec-based label Unidisc reissued most of the group's albums over a three-volume CD series.
The Canadian Encyclopedia entry for the group also lists a 1968 release entitled Total Lewdity, but this is erroneous.
