Mamya & greedykite. Thank you both very much. One lives and learns!, sorry not to have given letters but rumpi pumpy fits with the 'i' coming from the clue ' opposite of fame' = anonimity. Hence the 'i' in ;rumpi??
'I quite like 'hanky panky' sadly there are no fitting letters! So RUMPI PUMPI(Y) Gets it. Thanks again.
