"Wild One" suffered somewhat in sales as it was released just four months after the monster hit "Dancing In The Street". Many radio stations were still playing that record.
Background
The song, which in lead singer Martha Reeves' description, was a tribute to bikers (released shortly after The Shangri-Las' "Leader of the Pack"), described the narrator's strong love for her "wild one" who is told he's "no good" by the narrator's close circle. The narrator tells her "wild one" to not listen to what others say and continue to "sav(ing his) love for (her)".
Cash Boxsaid that the "storyline concerns a gal who digs a 'victim of circumstance'" and that the song has the "flavor of" the group's recent hit "Dancing in the Streets."[2]
