Stevie Wonder's contact to appear at the Cavern, Liverpool has recently come to light. Search under google for details. A poster advertising Alvin Cash there has also surfaced, go to this site's search option, type in Modus, hit archive poster exhibition, then poster exhibition pdf. There's also a great Spellbinders poster on Modus somewhere that also came from the Cavern source..

Thats a bit convoluted for me, I've had a beer, any chance of a link?

here's a link to the event page, get to that and the pdf is on that
