If ever a band was born to have its bones bared on the web it was The Smiths. There are too many Smiths-orientated websites to even begin listing them all, good or bad, but a trawl through any search engine will throw up the best. The majority of the bands and artists here have official sites and active Facebook and Twitter pages. www.thethe.com updates resources on Matt Johnson regularly, www.petshopboys.co.uk likewise for Tennant and Lowe, while www.kirstymaccoll.com and www.billybragg.co.uk are invaluable for these artists. David Byrne and Paul Carrack can be found at www.davidbyrne.com and www.paulcarrack.net respectively.
Johnny himself is of course at www.johnnymarr.com and is active on Twitter at @Johnny_Marr. Another excellent resource is the unofficial site www.johnnymarrplaysguitar.com. Official sites, Facebook pages and Twitter accounts can all be found for The Cribs, Modest Mouse, Neil Finn and most of the other artists referenced.
