I have so many questions and I know Mark doesn't have time to answer them, but let me try lol
On Sidewalk Surfin, apparently Jan did write some of it but couldn't receive credit because it was published by Sea of Tunes. Outside of a few lyrics, did Jan write the music for the instrumental break? It's different from Catch a Wave, so I figured Jan came up with it.
Also, who is doubling with Jan on Honolulu Lulu? Tony?
