Diane Linney's crystal clear vocals vividly portray the melancholy of youth and the anxiety of love.
"Navy Blue" is a heartbreaking ballad about a girl's feelings for her boyfriend in his school uniform, and resonated with teenagers of the time. The lyrics, along with the B-side "Unbelievable Guy," are memorable for their frank expression of a young girl's delicate emotions. This single was a testament to Linney's individuality in the girl pop scene of 1964.
