My band (Surf School Dropouts) has a x-mas EP out chock full of Beach Boys vibes. Hope you'll check it out!
https://open.spotify.com/album/29GrVz4Ji3JT0reCBz0xOR?si=iVVjtOnjRMiz1Kegp-GX8wLead-off track 'The Man in Red' is in a Little Saint Nick-vein and we sprinkled a bit of Smile-inspiration on to the final track, the instrumental 'Copenhagen Christmas',... also went for a Spector wall of sound-approach on 'Help Me Santa' and 'Another Christmas with You'
If you don't have Spotify the EP can be streamed / purchased off Bandcamp:
