In reply to Ramblin dave:
From what I've been able to find
The list of onsighted routes is:
Point Blank (3 [more I think], safe-ish but scary); My Piano (2, bold); Hollow Man (1, bold); Boldness Through Ignorance (1, bold - it's a solo); maybe Gaia [by Alex Honnold] (1, bold).
The other routes I've seen mentioned either weren't onsighted (as stated by the climbers themselves!) or, in the case of Dawes Rides..., was actually given E7 by the first ascentionist and only upgraded by someone who had never been on it (see also Caff's and Steve's comments).
