Another of those songs that is commonly criticized and seen as a filler track. I really like the track! Sure, it's kinda dumb, but it's also a ton of fun. Just like some of the other songs on the album, I wouldn't have wanted Maiden to permanently change course and only record music like that, but I'm glad and so happy that we have these one-offs into styles they usually don't play, songs they normally wouldn't write.
The intro riff, also used for the chorus, is super catchy. The verse is simple, but builds upon the same melodic ideas. The pre-chorus lets Bruce stretch a bit vocally and the chorus let's him properly soar for a little bit. We also get some cheesy gang vocals again. As I said, not something I'd want regularly, but hell, the chorus here gives me the biggest grin. The lyrics are on the weaker side, but they fit the music.
The section that follows afterwards is surprising and not what I would've expected from such a song. It has an ethereal and floating feel to it, with some nice vocalizations by Bruce, a lead guitar having some fun while acoustic guitars accompany everything. After that we get a solo section for good measure. Finally, some more choruses and a hilariously drawn out last vocal line with some slooow vibrato.
While a great song overall, without apparent weaknesses like the previous song, the composition is not an all time great. It's still enough for a 7, but not more than that.
