Lyric discussion by Whitchity Man 

Cover art for Sunshine lyrics by Alice in Chains

No relation, I'd say the songs about Layne's father. "Then some dude came down to touch the Mother Mother touched and dude ain't here no more." I think refers to how Layne's father met Layne's mother, had sex with her (touched the mother), then she had Layne, and then Layne's father left (Dude ain't here no more).
