The song "Travelling" by John Mayall is about exploration and adventure. It describes the excitement of packing a bag and embarking on a journey, not knowing what lies ahead but eager to discover new places and experiences. The lyrics mention the "Hinterlands," which refers to remote regions of a country that are unexplored or unknown. This suggests that the traveler is seeking out new and uncharted territory. The song also emphasizes the unpredictable nature of travel, including flying over icy seas and encountering snowfall. Despite this, the traveler is prepared with warm clothing and is not deterred from experiencing all that the journey has to offer. Towards the end of the song, the lyrics reflect a desire to see as much as possible before it is too late. This could be interpreted as a sense of urgency to live life to the fullest and embrace new experiences while they are still available. Overall, "Travelling" is an ode to wanderlust and the thrill of discovery, encouraging listeners to embrace adventure and take risks in their own lives.
