This is the first recorded version of what would become Iron Maiden's trademark song. This recording is much more raw than the version that eventually ended up on the first album, with a slower tempo that almost seems to drag a bit in places. However, it exhibits the raw power and energy of the early Iron Maiden recordings.
"Invasion" is another of Harris's early compositions, and was first recorded here on the Soundhouse Tapes. It is a great song about a Viking invasion, which was later released as a b-side to the Women In Uniform single, and which later evolved into "Invaders" on the Number Of The Beast album. This original version of "Invasion" has a slightly slower tempo than the later version, but is every bit as good.
This is the earliest version of "Prowler", a classic Iron Maiden song with an incredibly catchy tune. It was later re-recorded at a faster tempo for the Iron Maiden album, which improved somewhat on this raw version whose slower tempo seems to drag in places. Dave Murray's great guitar solo is here though, along with the raw energy that characterised Maiden's earliest recordings.
