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.
There are differences to the labels as well just like on the two different corresponding promo releases.
The one pressed at Rockaway hasn't got "Arr. by Jerry Vance" underneath the "Produced by Perception Prod." credit on the right side.
