Shelley! was released in June 1962. One month after its release the album charted at #106 on the Billboard 200 Chart. The first single taken from Shelley! was "Johnny Angel", and it was performed by Fabares on The Donna Reed Show during the show's fourth season. The song was released shortly before her Shelley! album and became a #1 US Hot 100 hit for two weeks on the pop chart. "Johnny Angel" sold over a million copies and was awarded a gold disc. "Johnny Angel" also charted at #41 on the UK Singles Chart and peaked at #1 in Canada. Fabares lip-synched her hit single on American Bandstand during a June 19, 1962 television appearance to promote her debut album.
The Shelley! album was released on Compact Disc in its entirety for the first time as part of a 2 LPs on 1-CD set released by Collectables in September 2000. This included the original liner notes from the 1962 album.
