What years did Terry King sing with the Drifters?

Well if you listen to Ron Terry he did. However a radio presenter on the Costa del Sol in Spain did some research and came up with the following. Ron Terry was a backing singer on one of thir records. If you ever go on holiday to Spain or the Med then every resort seems to have one of the original Drifters. If this is the case then there must have been about 20 in the drifters, and not 4 as originaly thought.
