Ultra Sound, who worked very  frequently in Birmingham  were a Coventry band who also worked all over the Midlands, and in the  Worcestershire, Staffordshire, Oxfordhire and Buckinghamsire areas. They were semi-pro with daytime jobs but worked 4 nights per week for most of the year. Saturday night gigs were often in Birmingham, at Club Cedar, or The Rainbow Suite or at any number of smaller venues across the city, as most of the work was sourced from Mike Carrol and Doug Thompson’s Birmingham based agencies.

Many Saturday afternoons were spent mingling with other musicians at the Jones and Crossland shop where the Park equipment they used originated.

From 1967 the line up was Brian Whittle on lead guitar, Paul Morton Drums/Lead vocal, and Dave Walker on Bass guitar. In 1969 Dave left and was replaced by Malc Harker.  For a couple of years up to late autumn 1969 Barrie Mansel-Edwards was Roadie and Biological Sound to Light Unit, ( in the days before the microprocessor took over the world).
It was around 1970 when the group broke up, and Malc Harker joined the Prog Rock group Indian Summer.

Thanks to Barrie Mansel-Edwards for the info

Some more memories of Ultra Sound from Barrie:

I do have some photographs of Ultra Sound, which Brian Whittle had kept, including one I was told included me (Barrie Mansel-Edwards).
When I finally got to see them around 4 years ago, there was a very nice shot of the three musicians Brain Whittle,
 Paul Moreton and Malc Harker, and another one with all the four of us, deliberately under exposed to give an Andy Warhol ambiance, hence it could be anyone. To add to the annoyance, using the other photo for comparison you can easily recognise the other three.
I also have one of Paul Moreton in an Arthur Fonzarelli pose, which was the flyer for a two gig spoof band called Danny and The Hearthrobs, for which several local bands had combined to perform a spoof of Danny And The Juniors.
The first gig was more or less a public rehearsal at the Lanch’ in a room in which live music was subsequently banned due to foot stamping in time to the band, which had caused significant structural damage. The second and final gig was at the February 1970 Lanchester Polytechnic Arts Festival.
The idea was Malc Harker’s, and he had recruited several other musicians to dress in drape coats, bootlace ties and brothel creeper shoes, to join himself and Brian Whittle to provide saxaphones, keyboards etc, backing Paul, who had abandoned his drums to be the lead singer “Danny”.
Out in front, with long hair bundled into sticky-up pigtails, were Bob Jackson (Indian Summer, Badfinger and The Fortunes) and Paul Hooper (Indian Summer and The Fortunes), in drag, dressed in frilly party dresses and wearing genuine pit boots (YES REALLY!), did hand jive to set the mood. Mid gig, Paul Hooper gave birth to a woolly jumper he had stuffed up his dress.
I (Barrie Mansel-Edwards) was dressed in borrowed biker gear as a Hells Angel look-alike Roadie, just wandering about the stage (irrespective of who was on), and accompanied  on stage by my miniskirted, long-legged girlfriend Lorna. Whilst not actually Top Of The Bill, Danny and Co were on last,  (following on from Free, Yes and Mott The Hoople).
The sight of a few hundred hippy-style students, and a large contingent from the famous Mothers of Erdington, almost resulted in the band being pulled, as one of the band members was in fear of a hostile crowd. I intervened and advised that the reaction might be far worse if they didn’t go on, so it happened.
The crowd  reaction was amazing, and after repeated  calls for encores, the organisers finally had to litterally cut the power, due to legal restrictions as the clock tipped beyond the permitted hour.
A representative from the Bron Agency, whom I think were there with Free, tried to sign the band, but the varied responsibilities of a diverse group of individuals made this an impossibility. One of Free made a paper flower for my girlfriend Lorna, which she lost.
The really awesome thing was that the next issue of Melody Maker had a review of the gig, saying “the hit of the night was Danny and The Throbettes ( !) with their Hells Angel Roadie”. I can’t remember who the many other band members were, other than Tim James, on Sax, who says he did not actually play a note that night.
