"Last Summer" is the fourth single from Start Something, the second album by the Welshrock band Lostprophets. The previous singles, "Burn Burn", "Last Train Home" and "Wake Up (Make a Move)" had all been highly successful on both sides of the Atlantic so this single was under similar pressure; it reached number 13 in the UK Singles Chart. The song describes the band members enjoying memories past of visiting towns in South Wales such as the seaside town of Porthcawl.
The music video, directed by The Malloys,[citation needed] shows lead singer Ian Watkins driving around Venice, California on the last day of the summer school term. He is driving a car with the plate number 2BAI222. The same plate number is featured in episode 1 of Numb3rs and episode 1 in the second season of The OC. As Watkins reaches his destination, the beach, he then goes back to the beginning and drives past the school again but in a different decade — the '70s, '80s, and the present. Around the 3:12 mark, lead singer Daryl Palumbo and bassist Jarvis Morgan Holden of Glassjaw and Head Automatica, respectively, can be seen walking in front of the school. Also at the 2:04 mark the metal band Steel Panther (performing at the time under the name Metal Skool) are seen in front of the school.
