I always loved 'Maroc 7', that and 'Tomorrow's Cancelled' were criminally overlooked singles - tho' by 1967 guitar led instrumentals had sadly - and wrongly - become seen as 'old hat' ( as indeed being a 'Mersybeat' group also had done - just ask The Searchers !)
The sixties 'turned and twisted' in all directions continually style wise ...by 1969 even acts from 1966 looked dated !
The Shads had somehow got a 'bow ties and tuxedos' image that doing pantos didn't help them either ....
I can't imagine say The Yardbirds or Pretty Things doing 'Cinderella' or 'Puss in Boots' or as puppets in Gerry Anderson 'Thunderbirds' films somehow !
sadly all this must have 'distanced' The Shads from being seen as contemporary or 'cool' in a good few young people's eyes mid sixties and probably stopped them listening to tracks they might well have enjoyed, hence the more adventurous Shads later sixties singles were overlooked by many I feel...
Why they never put fine tracks like; 'Late Night Set', 'Running Out of World', ' or even the excellent production job 'Trying To Forget The One You Love' as the singles 'A' sides is beyond me....
