1010 (Rin Tin Tin) is an unreleased song, recorded in 2010 at Paisley Park Studios in Chanhassen, Minnesota (But possibly recorded as early as 1994 or 1995.)
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. 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.
In 2011, 1010 (Rin Tin Tin) was planned to be included on the Welcome 2 America album that remains unreleased.
