Output from Australian Oi! Band who took the whole scene by storm! "Songs of yesterday" sounds like - well - it sounds amazingly like songs from an era long time ago.
If you are listening to Punk music today you surely often have the feeling that all the good songs were written at the end of the 70ies or the early 80ies? MARCHING ORDERS sound like a band out of this time, especially vocals from Al.
The cover song by THE PROFESSIONALS - "Mods, Punks, Skins" - fits perfectly into the "old" Punk feeling.
