Portishead's Influentual Nod to Journey?

Not sure if many of you are familiar with the band Portishead. I started playing their Pandora mix as chill background music while at work. Anyway, I just heard a song of theirs called Glory Box. Couldn't help but notice a strong similarity to You're On Your Own from the Look Into the Future album. The melody is very unique….IMO too much of a coincidence for it not to be an influence.
Check 'em both out.
