And what about "Ferry Cross the Mersey"?
I like that song...
I'm not a huge Hermans Hermits fan, but "No Milk Today" has always been one of my favorite all-time songs for whatever reason. (flip of the 45 = "There's a Kind of Hush" which I like, too, but I did not play as much as the B side)
A bit of trivia: my son lived for a few years in and around Merseyside in the late 90s. He often took that "ferry 'cross the Mersey." He said the ferry owner has that song piped on permanent loop throught the ferry loudspeaker system. I don't care what the reason. Playing any song that much is pathological.
As for a song with great opening riff that always picks me up, "Money for Nothing" by Dire Straits is right near the top.
