"When I'm with You" is a power ballad by Canadian arena rock band Sheriff. A top ten hit in Canada in 1983, It hit number one in the United States in 1989, four years after the band separated.

The song first appeared on Sheriff's self-titled debut album (the group's only album, to date), released in 1982. It was released as a single but failed to make a big impression on the charts at the time.

After the success of "When I'm with You" several years later, Freddy Curci (lead vocalist) and Steve DeMarchi (lead guitarist) tried to put Sheriff back together, but the other band members would not release permission for use of the band name. Consequently, Curci and DeMarchi formed the band Alias, which would have a hit in 1990 with the power ballad "More Than Words Can Say."

Freddy Curci is listed in the Guinness Book of Records for holding the longest note in a pop song, timed and submitted by a Houston university, at the ending line of "When I'm with You."

This song is also notable that it was one of the few #1 hits not to have a promotional video in the MTV era.

#1 back in 1989 - how about today?
