Backless is the sixth full-length studio album by Eric Clapton. Produced by Glyn Johns, and released by RSO Records, Backless reached No. 8 on the pop charts. While the single "Promises" only reached No. 37 in the UK, it was a much bigger success in the US, reaching No. 9 on the Billboard charts. The follow-up single, "Watch Out for Lucy", was the B-side of "Promises", but reached No. 40 on the Billboard charts on its own merit. Later in 1980 "Tulsa Time" was US #30 with 1977 song "Cocaine" as B-side. It was Clapton's last studio album to feature his longtime bassist Carl Radle who died in 1980.
