Paul Lavon Davis (April 21, 1948 – April 22, 2008) was an American singer and songwriter, best known for his radio hits and solo career which started worldwide in 1970. His career encompassed soul, country, and pop music. Typically, the slower the tempo of a Davis record, the longer it took to reach its peak position. His most successful songs are 1977's "I Go Crazy", a #7 pop hit which once held the record for the longest chart run on the Billboard Hot 100, and 1982's "'65 Love Affair", which at #6 is his highest-charting single. In the mid-1980s, he also had two country #1 hits as a guest vocalist on songs by Marie Osmond and Tanya Tucker.
