I'd agree she cut some great material. Caught Up, in particular, was stunning when it came out. But my feeling is she had the potential to rank among the greats but let herself down through choice of songs.
I saw her around 78 in Brum, and, refelecting on it now, all that raunchy, sassy, shoot from the hip, kinda schtick was so unnecessary, and, frankly a tad toe-curling.
Oh - and the last thing I am is a prude!
