1010 (Rin Tin Tin) is the tenth song of the tenth posthumous album Welcome 2 America (the first full previously-unreleased studio album of Prince material).
While specific recording dates are not known, basic tracking most likely took place in March/April 2010 at Paisley Park Studios in Chanhassen, Minnesota. This is the only song on the album to feature Prince as the sole musician (without Tal Wilkenfeld, Chris Coleman and/or John Blackwell).
In the 2017 Prince Exhibit "My Name Is Prince" at the O2 in London, England, lyrics of this song were on display, including noting of verses and a key of F, for it to be played in. A line of the lyrics reads: "If u ask the Lone Ranger Rin Tin Tin (1010)", with 1010 could be Prince shorthand for (Rin)TinTin and a play on words with the angelical number 1010. Also in that line the L in Lone Ranger is corrected from a B. Bone ranger is a pun that also occurs in the lyrics to 18 & Over.
