the website is clear about the  3:30 pm interview shows 
but couldn't find anything re: content of the 12:30 live webcast ... anyone know who / what ?
just trying to determine if will want to tune in at 3:30 or 6:30 in my eastern time zone 

<i>btw : check out their archived Lounge shows - listening to John Hiatt's session at moment - quite interesting</i>
