I went to university in my mid-thirties with the same fears as you.
But it turned out that the student age-range was very diverse and, anyway, who I got on with socially was not determined by age alone.
Having said that, it pays not to be nor to appear to be a 'pompous old git' - which I am sure you're not.
As for being 'on a totally different wavelength', there are people of your own age 'on a totally different wavelength'.
Good luck with it.
Yes, and by '78, as well as the solo album, there were three Weather Report albums with Pastorius appearing on at least some tracks.
Many of the musos I knew were listening especially to Weather Report, in particular Heavy Weather.
The idea that Pastorius wasn't influential (in listening and playing) by 1978 is ridiculous. It has its limits but its there.
I took the pickup guards off too. In my experience it was common to take them off. Took it off Fenders too.
Several rock bassists used fretless basses. They are in a minority but you're incorrect to say rock bands never used fretless.
Guitar is sometimes slightly too forward, if you ask me, but bass sounds fine, especially on Ticket, nice tone.
Occasionally, e.g. Come Back Down, bass could be a little more prominent but still ok I'd say.
I remember Jones & Crossland.
And George Clay in Broad Street.
And Wasp on Bristol Street with Nest Studio underneath.
And some others that I don't recall the names of.
