Pictures of Blue Letter D - stargate-rasa.info

Some speculate that the “Blue Letter” may be about leaving a lover for someone younger. Although it wasn’t written by Lindsey Buckingham and Stevie Nicks primarily, there are those that believe that this song ties into their famously tumultuous romance. The couple's eventual breakup after years of drama came to characterize Fleetwood Mac's legacy, and they were having difficulties in their relationship as early as 1975 when they recorded "Blue Letter". It is possible that this vaguely antagonistic track foreshadows more explicit breakup songs such as the Rumours hit, “Go Your Own Way”. However, the band’s comparative lack of public dialogue on the track combined with its more figurative lyrics make it impossible to discern any one true meaning.
