     File Header:

-        the 56th byte, can change but no real meaning has been found. The
-        56th byte specifies how many blocks there are. The first block starts
-        with byte 83 after the "CSongDoc::CBlock" declaration.
+        Bytes are counted from one, i.e. the first byte is byte 1.

+        0x20 - 0x2B Minimum version of Words Of Worship required to save this file without data loss
+        0x2C - 0x37 The version of Words of Worship that this file is from. From test data, it looks like this might be
+                    the version that originally created this file, not the last version to save it.
+
+        The Words Of Worship versioning system seems to be in the format:
+            ``Major.Minor.Patch``
+
+        Where each part of the version number is stored by a 32-bit int
+
+        0x38 - 0x3B Specifies how many blocks there are.
+
+        0x42 - 0x51 Should be "CSongDoc::CBlock"
+
+        0x52 The first song blocks start from here.
 
     Blocks:
-        Each block has a starting header, some lines of text, and an ending
-        footer. Each block starts with a 32 bit number, which specifies how
-        many lines are in that block.
+        Each block starts with a 32-bit int which specifies how many lines are in that block.
+
+        Then there are a number of lines corresponding to the value above.
 
         Each block ends with a 32 bit number, which defines what type of
         block it is:
 
-        * ``NUL`` (0x00) - Verse
-        * ``SOH`` (0x01) - Chorus
-        * ``STX`` (0x02) - Bridge
+        * 0x00000000 = Verse
+        * 0x01000000 = Chorus
+        * 0x02000000 = Bridge
 
         Blocks are separated by two bytes. The first byte is 0x01, and the
         second byte is 0x80.
 
     Lines:
-        Each line starts with a byte which specifies how long that line is,
-        the line text, and ends with a null byte.
+        Each line consists of a "Pascal" string.
+        In later versions, a byte follows which denotes the formatting of the line:
+
+        * 0x00 = Normal
+        * 0x01 = Minor
+
+        It looks like this may have been introduced in Words of Worship song version 2.1.0, though this is an educated
+        guess.
 
     Footer:
-        The footer follows on after the last block, the first byte specifies
-        the length of the author text, followed by the author text, if
-        this byte is null, then there is no author text. The byte after the
-        author text specifies the length of the copyright text, followed
-        by the copyright text.
-
-        The file is ended with four null bytes.
+        The footer follows on after the last block. Its format is as follows:
+
+        Author String (as a 'Pascal' string)
+        Copyright String (as a 'Pascal' string)
+
+        Finally in newer versions of Word Of Worship song files there is a 32 bit int describing the copyright.
+
+            0x00000000 = Covered by CCL
+            0x01000000 = Authors explicit permission
+            0x02000000 = Public Domain
+            0x03000000 = Copyright expired
+            0x04000000 = Other
+
+    Pascal Strings:
+        Strings are preceded by a variable length integer which specifies how many bytes are in the string. An example
+        of the variable length integer is below.
