Sung regularly by Pigpen with the Grateful Dead, but not revived by them after he died (except for a couple of performances with Etta James). But subsequently played by The Other Ones, Phil Lesh & Friends and The Dead. Pigpen sang the verses pretty much the same each time, though the rap in the middle varied - this is from the version on "Bear's Choice":
Baby here I am and I'm a man upon the scene
I can give you what you want, but you got to come home with me
I got a whole lot of good ole loving and I got some in store
When I get through throwin' it on to you got to come back for more
Boys and things will come by the dozen
Ain't nothin' but drug store love
Pretty little thing let me light your candle
Cause mama I'm sure hard to handle, now yes I am.
Action speaks louder than words and I'm a man with great experience
I know you got another man, but I can love you better than him
Take my hand, don't be afraid I'm gonna prove every word I say
I'm advertising love for free so won't you place your ad with me?
Boys and things will come by the dozen
Ain't nothin' but drug store love
Pretty little thing let me light your candle
Give it to me baby, I got to have it, some of your love
It's all I need, early in the morning, late in the evening.
