I picked up on this when I first listened to the album in the year 2000. I thought even if the song had been written today it still wouldn't make sense. I understand what Crushden is saying how in 1991 he's just a happy child playing, but the way the song is sung it definately sounds like the kid was born in 1991. I guess it must apply to the latter lyric though to make any sense. Either that or it's just bullshit writing, which would go against the grain of TD, as it's not a bullshit album.
