The Watchmen were a Canadian rock band. They were one of the most commercially successful Canadian alternative rock groups of the mid to late 1990s.
The group was formed in 1988 in Winnipeg, Manitoba by vocalist Daniel Greaves, guitarist Joey Serlin, bassist Pete Loewen and Greaves' first cousin, drummer Sammy Kohn. Serlin was a comic fan and named the group after the DC comic.
The band toured Canada extensively and became a popular live act, largely on the strength of its energetic shows, which invariably featured an a cappella performance by Greaves at some point in the set. Greaves often covered songs by Billy Bragg, Simon and Garfunkel, Lyle Lovett, The La's, Tom Waits and others during these solo spots, and fans came to look forward to them as a highlight of each show. On rare occasions, Greaves performed more than one a cappella song in a set: at one 1998 performance broadcast live on radio, Greaves entertained the in-person audience during commercial breaks by singing Nicarauguan folk songs in addition to performing Billy Bragg's "Between The Wars."
