"Two's Company (Three Is Allowed)" is a song by Gilbert O'Sullivan that addresses various societal norms and expectations in relationships and sexual orientations. The lyrics touch upon themes like monogamy, gender roles, same-sex relationships, and individuality. The song begins by mentioning how Sellotape (a type of adhesive tape) is sticky, which may seem obvious. This line serves as a metaphor for the surprise and unexpected things in life. The next line humorously suggests that the next surprising statement could be as obvious as being able to see out of one's eyes. The lyrics then transition to discuss the concept of gender roles and identities. The phrase "Mummified mummies daddies little girl" refers to a person who, despite being assigned the gender of a girl at birth, had a sex reassignment surgery to transition into a man and eventually inherited the title of an earl. This highlights the idea of personal choices, self-expression, and the fluidity of gender roles. The song then challenges the traditional notions of romance and fidelity. It suggests that in the past, one would gently kiss their partner on the cheek, but now the roles are reversing, and intimacy starts with kissing the feet. This illustrates the evolving dynamics of relationships and challenges societal norms. The lyrics also touch upon the idea that monogamy is no longer seen as a strong commitment, with "kids" thinking of it as just another object, moving away from the emotional significance it used to hold. The chorus, "Two's company, three is allowed" is repeated throughout the song. It implies that traditional concepts of relationships (two people) are expanding, and there is room for more unconventional arrangements and perspectives. The song also addresses the changing perception of women in society. It suggests that women are now considered out of place if they don't identify as lesbians or have gay friends. It critiques the idea that being a lesbian or having gay friends should be a prerequisite for acceptance. The lyrics further touch upon the idea of normalcy and question what it truly means. Getting married only to plan a future divorce is cited as an example of how society has redefined and accepted unconventional practices as normal. The song briefly mentions twins and suggests that after seeing one, there isn't much difference in seeing the other. However, if one of the twins is exceptionally attractive, the song questions whether it's acceptable to be attracted to one while disliking the other. The lyrics conclude with a statement on personal style and individuality. O'Sullivan asserts his right to wear what he likes and intends to defy tradition by not wearing a suit or tie. This ties back to the overall theme of breaking societal expectations and embracing one's individuality. Overall, "Two's Company (Three Is Allowed)" explores societal norms, challenges traditional views on relationships and gender roles, and emphasizes the importance of personal identity and self-expression.
