I have no idea how or why this became such a massive hit. She was basically unknown in the UK. 'I'm a Sucker for Your Love' with Rick James did make #43 the year before. At the end of 1980 'I Need Your Lovin'' peaked at #28, it was to be her final Top 50 UK hit. None of her albums ever charted either. Of course it was not the only time that Motown had a mystery one off massive hit in the UK. Yvonne Fair, who had no previous history in the UK, stormed to #5 in 1976. Sadly she never charted again! In 1982 Charlene Duncan shocked me by having a UK #1 with the tedious dirge 'I've Never Been To Me'. Thankfully she never troubled the UK charts again! (Sorry Eric, I know that you have a soft spot for her.)
