So Alone is the debut solo studio album by Johnny Thunders, then leader of the Heartbreakers and formerly lead guitarist for New York Dolls.

So Alone was preceded by the singles "Dead or Alive" and "You Can't Put Your Arms Round A Memory", the former originally being omitted from the album and later included as a bonus track on the 1992 reissue.

The album contained a mix of original songs, tracks regularly performed live by the Heartbreakers, and covers, including the Chantays' surf classic "Pipeline," the Shangri-Las' "Give Him a Great Big Kiss", Otis Blackwell's "Daddy Rollin' Stone", and New York Dolls' "Subway Train".

The song "You Can't Put Your Arms Around a Memory" is considered by many to be Thunders' signature song, and has later been covered by Guns N' Roses, Billie Joe Armstrong of Green Day, Ronnie Spector with Joey Ramone, and Nick Oliveri with both Queens of the Stone Age and Mondo Generator.

The track "London Boys" was written as an answer song/diss track from Thunders aimed at the Sex Pistols who had recorded a song called "New York" on their album Never Mind the Bollocks, Here's the Sex Pistols a year earlier, in which they anachronistically attacked Thunders's band New York Dolls for being rip-offs.
