The song "Memorial Day" by James McMurtry tells the story of a family's road trip to visit their grandmother on Memorial Day, a holiday in America to remember and honor fallen soldiers. Along the way, the family experiences typical family dynamics and conflicts, such as siblings fighting and grandma scolding. However, throughout the song, there is an underlying message to remember and honor those who have died fighting for their country. The lyrics paint a detailed picture of the family's journey, including the heat, the towels used to block out the sun, and the big yellow object on a trailer that the father nearly hits. The family members are also described, such as the mother trying to find a sports game on the radio and the father drinking a beer. Despite the family's conflicts, the song reminds listeners of the importance of Memorial Day and paying tribute to those who have sacrificed their lives for their country. The lyrics encourage drivers to "y'all be sure and drive slow" as a sign of respect. Overall, the song has a nostalgic and reflective tone, reminding listeners of the true meaning behind the holiday.
