This was sung by Elvin Bishop with the Dead on 6 June 1969. (thanks to Graham for sending me a recording)
Checkin' up on my baby
Find out what she's putting down
Checkin' up on my baby
Find out what she's putting down
Checkin' up on my baby
All those nights spent out of town
Checkin' up on my baby
Find out what she's putting down
Checkin' up on my baby
Find out what she's putting down
So many nights and days
I have been out of this town
Checkin' up on my baby
Find out what she's putting down
Checkin' up on my baby
Find out what she's putting down
So many nights and days
I have been out of this town
Checkin' up on my baby
Find out what she's putting down
So many nights and days
I have been out of this town
I'm gonna come home to her
Show her where it's at
And after I do that
I'm gonna leave this place
And I'm not gonna ... don't blow it now, don't blow it now
Keep it right here
Easy
Oom bam bam
Oom bam bam
[etc]
Feels so good
I get the feeling baby
And let me take it on home
