Leonard Arthur 'Lenny' Davidson (born 30 May 1944 in Enfield, Middlesex, England) is an English musician, best known as the guitarist for the Dave Clark Five.
According to Mike Smith (the DC5's lead singer and keyboardist), Dave Clark was looking for a lead guitarist and asked Smith if he knew anybody. Smith recommended Davidson saying there was no one better. Smith and Davidson had worked together in a previous band.
He was one of three members of the group who wrote songs. He wrote, their 1965 hit "Catch Us If You Can", and contributed five more tunes on the Having A Wild Weekend soundtrack album. He also contributed "Crying Over You" and "When" to their 1965 Coast to Coast album, and sang lead on the 1967 hit "Everybody Knows" which reached number 2 on the British charts.
Davidson was inducted as part of the group into the Rock and Roll Hall of Fame in March 2008 along with the then fellow surviving band members Dave Clark and Rick Huxley.
