Songfacts®:

• "Radioactive Toy" is one of the earliest Porcupine Tree songs, but also one of their most enduring, played at many of their concerts, often as an encore. It was first released in 1989 on Tarquin's Seaweed Farm, a homemade cassette, in a version running 5:55. The cassette made its way to a journalist named Richard Allen, who became the band's manager and issued their music on his Delirium label. The first Delirium release was the album On the Sunday of Life..., which includes an expanded, re-recorded version of "Radioactive Toy" running 10:19.
• Porcupine Tree was just one guy at the time: Steven Wilson, who wrote, produced, sang and played all the instruments on the track. The band was an exploratory project for him, but he put together an elaborate backstory with fake band members and a made-up history that was included in the liner notes to Tarquin's Seaweed Farm. The leader of the group was "The Porcupine Tree," and other members included Mr. Jelly and The Expanding Flan. On their next album, Up The Downstair in 1993, they became a real band.
• The song is about nuclear weapons and the fear that they will literally destroy the world. When Steven Wilson wrote the song, the Cold War was still going on and the threat of nuclear annihilation was very much on his mind. In particular, it was inspired by a 1984 movie called Threads that depicts a nuclear war.
• This was the first Porcupine Tree song to earn airplay: The BBC DJ Mark Radcliffe loved the song and often played it on his show.
