In Europe, the band toured with Aerosmith, and in the US, after releasing another single "Sun King" (UK No. 42), they spent 1989 touring in support of Metallica before heading out on their own headlining tour later that same year. A fourth single, "Sweet Soul Sister" (UK No. 38), was released in February 1990, with the video having been filmed at Wembley Arena, London, on 25 November 1989. "Sweet Soul Sister" was partially written in Paris and was inspired by the bohemian lifestyle of that city. Released as a single in February 1990, the song was another hit in the UK, and reportedly reached number one on the rock charts in Brazil. After playing a show in Atlanta, Georgia, in February 1990, the band's management told Astbury that his father had just died of cancer. As a result, the remainder of the tour was cancelled after a final leg of shows were performed in April. After the tour ended, the band were on the verge of splitting due to Stewart retiring and moving to Canada to be with his wife, and Sorum leaving to join Guns N' Roses.
