You Always Come Through for Me, Sweetheart
"You Always Come Through for Me, Sweetheart" is a song performed by Buffy on Sesame Street in Episode 1350.
Buffy complains to her Muppet beagle friend (performed by Jerry Nelson) how she wants to hang out with someone while she practices her Apache fiddle. The dog gives a positive response with happy panting and wagging tail, and Buffy shows her appreciation by singing about how loyal they are to each other. The dog joins in singing in English and howling, giving Buffy a lick at the song's end.
Buffy had previously performed with the Muppet beagle years prior when they sung "My Jim Dog" as a duet.
