no, i wouldn't consider the proposed change to the 1960s section acceptable ("Two key bands little known bands ... whose leads singers had both idolized him as teens", i mean) - it's too promotional/unencyclopedic in tone, and the article doesn't need more of that. 
regarding the Pickett quote: as i've pointed out repeatedly, it's not only the fact that it's from a blog that's problematic - it's also misrepresented: what it says is that Max Pickett said Wilson once called Little Richard that.  you can't use that to support the assertion now in the article.  as for the Bo quote: maybe that's more promising - is that the complete statement reported in White?
