Red Hot Chili Peppers increased ''morale'' by writing new songs while their tour is delayed.

The 'Under The Bridge' group had to postpone their US dates from January to the end of this month after frontman Anthony Kiedis injured his foot, and drummer Chad Smith said they took advantage of the time off to start on new tracks.

He told ''We just rehearsed and came up with some ideas and new song ideas.

''It's good for morale, it's good for the future. The future is bright.

''Normally in Chili Peppers world we never really had this much of a kind of break in a tour. Before, if we had a month off, we would never get together and write song ideas. But everyone just wanted to play. It was great.''

Chad - who is in the group with Anthony, bassist Flea and guitarist Josh Klinghoffer - also confirmed former axeman John Frusciante, a member of the band for their most popular albums, 'Blood Sugar Sex Magik','Californication', and 'By the Way', will not attend when they are inducted into The Rock 'n' Roll Hall of Fame in April.

He added: ''He didn't feel comfortable coming, which we totally respect.

''We asked him, he said, 'I'm just not really comfortable with that, but good luck and thanks for inviting me.'

''He's the kind of guy, I think, that once he's finished with something he's just on to the next phase of his life. The Chili Peppers are not really on his radar right now.''

However, former band members Jack Irons and Cliff Martinez will be in attendance for the introduction.
