Sloan, one of Canada's top pop/rock bands, recently released a double live album, 4 Nights at the Palais Royale. In the liner notes, they talk a little about each of the songs:

KEEP ON THINKIN':
Chris: This potboiler is in the trilogy of songs from Navy Blues that are too high for me to sing. True to form, I can barely make my way through this version either. I wanted Jay to take an acoustic guitar and a capo on tour for this song. I got the capo but I assumed he didn't like the look of himself with an acoustic because we never brought one (and maybe there are no pictures of Johnny Marr with one). In the end, he wouldn't mind using one, we just never bought one.

It's interesting to see just how far reaching the Smiths' influence has been on today's pop/rock groups.
