All time great. evergreen R&B dancer from the legendary Johnny Guitar Watson. With its call and response vocals and snappy riff. on I Say I Love You Watson comes across a little like Ray Charles with more casual. streetwise attitude. And don t let the middle tempo fool you. this is about as infectious as it gets and a guaranteed floor filler every time. On the flip. Sweet Lovin Mama is another cool R&B side that Watson cut for King Records in the early 60s - slightly less known than I Say I Love You but ripe for a little more exposure.
