Cobain began developing an interest in music at a young age. According to his aunt Mari, he began singing at the age of two. At age four, he started playing the piano and singing, writing a song about a trip to a local park. He listened to artists like the Ramones and Electric Light Orchestra (ELO), and, from a young age, would sing songs like Arlo Guthrie's "Motorcycle Song", The Beatles' "Hey Jude", Terry Jacks' "Seasons in the Sun", and the theme song to the television show of the band The Monkees.
