Resources & Acknowledgements
There are many useful Beach Boys reference sites out their - including Andrew Doe's Bellagio site and Beach Boys Legacy.
Three forums may be of interest - Steve Hoffman's forum for more general rock chat, and the Smiley Smile and Endless Harmony forums for Beach Boys chat.
Also useful more generally was Wikipedia and Discogs, so thanks to anyone who contributes to those sites.
Special thanks to Dogear for his list on 45cat and JK for constantly finding interesting non-English covers.
And finally, thanks to those who have messaged me with covers to add.
A large amount of this code-base can be found on Github.
Code-wise, this site makes use of StupidTable and some responsive table features was based around Smashing Magazine's and Adrian Roselli's articles on the matter.
