Ron Hackling co-wrote The Mark V's harmony garage-pop nugget "I Want To Say" on the Blast label:
Hackling seems to have been involved with The Duprees (a.k.a Italian Asphalt & Pavement Co / I.A.P. Co.) in some way as well, turning up as producer and co-writer together with Tommy Petillo on a few late tracks.
There's quite a bit of latter day footage of Ron Hackling performing on YouTube.
