Barclay James Harvest !
Initially they intended to be proggers. There's even a short concert film with them (shot by Wim Wenders in about 1970, btw.) that shows them playing really ambitious music. But then, as we all know: Sticky sweet soft pop. Moody Blues wannabees. Maximum WAF. Precautiously one has to put his speakers into a big enough tub to prevent the schmalz and syrup from distributing over the floor.
Best regards!
