Story on the recording including this on Brian...
But one thing was missing: Brian Wilson.
‘THEY JUST SAID, HE’S NOT AVAILABLE’
The original version of “Add Some Music to Your Day” was mainly written by Wilson (the Beach Boys’ founding songwriter, co-lead vocalist and former bandleader) and Love.
Vocals on the song were sung by Wilson, Love, Johnston, Jardine and Wilson’s brothers Carl and Dennis. Dennis Wilson died in 1983; Carl Wilson died in 1998. Beard wanted Brian Wilson to be involved in the new version of the song. Badly.
It wasn’t meant to be, however.
“I was told Brian wasn’t available. I asked twice. Just was told he wasn’t available,” Beard says.
“I’m assuming because of the pandemic. I’m assuming that. I don’t know. I’m not going to pry. It’s not my business. If it’s my business then they would say, ‘He’s not available because of this.’ They didn’t say that to me. They just said, ‘He’s not available.’ ... I just — you hear no twice ... you don’t want to upset anybody, because if you’re either upsetting somebody or manipulating somebody, you’ve lost your intention.”
