This website is the ‘English Broadside Ballad Archive’ site and takes you to a Ballad called: ‘London Mourning in Ashes’ Ballads such as this were written at the time and printed much like our newspapers today.  These ‘news’ stories would be sung to well known tunes (the closest tune that still exists today would be something like ‘Green sleeves’) Samuel Pepys was a well known collector of Broadside Ballads.
