Iron Man & Ultron singing in 1985 movie 'Tuff Turf'

This a movie from 1985 called 'Tuff Turf' starring James Spader & Robert Downey Jnr. I actually went to the movies twice to see it (I was a teenager) and thought it was awesome! Now looking at it, I realise how crap it is, and how great it is, as an 80s move! This is the part where James Spader spontaneously sings a song to his girl called 'We walk the night'. Could anything be lame & 80s cool at the same time?
