It was the first release from their sixth studio LP, A Rock and Roll Alternative.
In "So in to You", the singer admits an instant and mysteriously compelling attraction to a stranger entering the room, and is unable to focus on anything else.
He attempts to gain the stranger's attention, hoping that she will be able to make a personal connection and that the "vibe" he feels will be mutual.
It has been rumored that the woman in real life was Leslie Hawkins, one of the "Honkettes" back-up singers of Lynyrd Skynyrd and that drummer Robert Nix was smitten with her.
It did best in Canada, where it reached number 2,[3] blocked from the top only by the Eagles' "Hotel California".
