Gagarin's Start at Baikonur holds a 23:32 record between launching the 3rd and 4th Soviet human spaceflight missions, Vostok-3 and Vostok-4.
Gherman Titov was the second human to orbit the Earth, launching aboard Vostok 2 in August 1961 at the age of 25.
The first music performed in space was by Soviet cosmonaut Pavel Popovich, who sang a Ukrainian song on Vostok 4 in 1962.
