 Perry and The Upsetters toured the United Kingdom to capitalise on the success of Perry's hit "Return of Django" (and the less successful follow-up, "Live Injection"); returning to Jamaica in 1970.As part of The Upsetters, Adams backed The Wailers during their spell with Perry and Adams did much of the arranging and composed the song "Mr. Brown".The lyrics were inspired by a local tale about a duppy who was supposedly seen speeding around on a three-wheeled coffin with two "John Crows" (buzzards) on top, one of which would ask for "Mr. Brown".
