:Admin help? Odd really. (BTW I am not one.)  
 :Trouble section? "The band was formed following the dissolution of the brother's previous band, the AC/DC influenced Rock Pirates formed in 2004 with guitarist Tom Johnson who were describe as an "irony-free Darkness with bare torsos and blond highlights" 
 :Did the Family Rain not start after Rock Pirates? The sources doesnt mention this, but a basic calculation of band finish-start dates would confirm its correct. 
 :Also the sources qouted use "AC/DC influenced" and "irony-free Darkness with bare torsos and blond highlights", so these are both sourced and varifable.  
 :Will's opionion "Although I acknowledge myself and my brother were in these other bands as people there is no purpose, reason or justification for that information being on the family rain Wikipedia page." Why? It is varifable and sourced, you cant change the past, even more so in the digital media age. 
 :Will's reason "I feel that information on previous projects (especially given that it is taking up a large proportion of a currently locked Wikipedia page) is not relevant to my notability and is damaging to my reputation, which is why I have requested its removal." Have you also requested that the websites that have been used as sources also retract thier coverage of you? It takes up a small portion, and mentioning of previous bands is a common practice on here.  
 :I would be in the opinion of its souced and correct- it stays.
